99386658 divided by 812 
Our goal is to divide 99386658 by 812.

Moving on to step 1:
812 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 812

Advancing to step 2:
812 goes into 99 0 times with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 812

Going ahead to step 3:
The number 812 fits into 993 1 times, leaving a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 812 from 993, we get 181.
Bring next digit (8) of the dividend behind the 181 and repeat the process: 1818 / 812

Going ahead to step 4:
1818 divided by 812 is 2 with a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1624 from 1818, we get 194.
Grab the next digit (6) from the dividend, add it to 194, then carry on: 1946 / 812

On to step 5:
1946 divided by 812 is 2 with a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 322 after subtracting 1624 from 1946.
Include the next digit (6) from the dividend after 322, then repeat: 3226 / 812

Advancing to step 6:
The number 812 fits into 3226 3 times, leaving a remainder of 790.
The next digit of our result is 3. 
Result so far: 1223.0
Deduct 2436 from 3226 and we're left with 790.
Grab the next digit (5) from the dividend, add it to 790, then carry on: 7905 / 812

Advancing to step 7:
The number 812 fits into 7905 9 times, leaving a remainder of 597.
Record the quotient 9 as the next digit in the result. 
Result so far: 12239.0
The remainder is 597 after subtracting 7308 from 7905.
Take the next digit (8) from the dividend and append it to 597, then repeat: 5978 / 812

Going ahead to step 8:
812 can be fit into 5978 7 times, resulting in a remainder of 294.
Record the quotient 7 as the next digit in the result. 
Result so far: 122397.0
Subtracting 5684 from 5978 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 9:
If we divide 2940 by 812, we get 3 and a remainder of 504.
The number 3 becomes the next digit in our result. 
Result so far: 122397.3
Deduct 2436 from 2940 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 10:
5040 divided by 812 is 6 with a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 122397.36
Subtract 4872 from 5040 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 11:
812 goes into 1680 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 122397.362
If we take 1624 away from 1680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
If we divide 560 by 812, we get 0 and a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 122397.362
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
812 can be fit into 5600 6 times, resulting in a remainder of 728.
Record the quotient 6 as the next digit in the result. 
Result so far: 122397.36206
If we take 4872 away from 5600, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Moving on to step 14:
The number 812 fits into 7280 8 times, leaving a remainder of 784.
Use 8 as the next digit of our solution. 
Result so far: 122397.362068
Subtracting 6496 from 7280 leaves us with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Let's proceed to step 15:
812 goes into 7840 9 times with a remainder of 532.
Write down 9 as next digit of the result. 
Result so far: 122397.3620689
Subtracting 7308 from 7840 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 16:
When dividing 5320 by 812, we get 6 with a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 122397.36206896
The remainder is 448 after subtracting 4872 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

In conclusion, the division gives 122397.36206896 with a balance of 4.48e-07.
