We look at the division of 99355023 by 807 
We want to divide 99355023 by 807.

Moving on to step 1:
807 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 807

Moving on to step 2:
If we divide 99 by 807, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 807

On to step 3:
When dividing 993 by 807, we get 1 with a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 807 from 993, we get 186.
Append the next digit (5) from the dividend to 186 and continue with: 1865 / 807

Step 4:
If we divide 1865 by 807, we get 2 and a remainder of 251.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 251 after subtracting 1614 from 1865.
Include the next digit (5) from the dividend after 251, then repeat: 2515 / 807

Moving on to step 5:
The number 807 fits into 2515 3 times, leaving a remainder of 94.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 2421 away from 2515, we end up with 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 807

Going ahead to step 6:
The number 807 fits into 940 1 times, leaving a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 1231.0
If we subtract 807 from 940, we get 133.
Fetch the next digit (2) from the dividend, attach it to 133 and continue: 1332 / 807

Advancing to step 7:
The number 807 fits into 1332 1 times, leaving a remainder of 525.
Put 1 as the next digit of the answer. 
Result so far: 12311.0
If we take 807 away from 1332, we end up with 525.
Bring next digit (3) of the dividend behind the 525 and repeat the process: 5253 / 807

Let's proceed to step 8:
807 can be fit into 5253 6 times, resulting in a remainder of 411.
Put 6 as the next digit of the answer. 
Result so far: 123116.0
Deduct 4842 from 5253 and we're left with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Moving on to step 9:
807 can be fit into 4110 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 123116.5
The remainder is 75 after subtracting 4035 from 4110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
When dividing 750 by 807, we get 0 with a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 123116.5
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
807 goes into 7500 9 times with a remainder of 237.
The next digit of our result is 9. 
Result so far: 123116.509
If we take 7263 away from 7500, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 12:
If we divide 2370 by 807, we get 2 and a remainder of 756.
The next digit of our result is 2. 
Result so far: 123116.5092
Subtract 1614 from 2370 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Moving on to step 13:
If we divide 7560 by 807, we get 9 and a remainder of 297.
The next digit of our result is 9. 
Result so far: 123116.50929
Subtracting 7263 from 7560 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 14:
2970 divided by 807 is 3 with a remainder of 549.
Put 3 as the next digit of the answer. 
Result so far: 123116.509293
Deduct 2421 from 2970 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Step 15:
If we divide 5490 by 807, we get 6 and a remainder of 648.
Write down 6 as next digit of the result. 
Result so far: 123116.5092936
Deduct 4842 from 5490 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 16:
807 can be fit into 6480 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 123116.50929368
Subtracting 6456 from 6480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 123116.50929368, with a leftover of 2.4e-08.
