Let's divide 81599893 by 199
We want to figure out the number of times 81599893 can be divided by 199.

On to step 1:
If we divide 8 by 199, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 199

Moving on to step 2:
The number 199 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 199

Step 3:
If we divide 815 by 199, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 796 from 815 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 199

Advancing to step 4:
199 goes into 199 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we take 199 away from 199, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 199

Going ahead to step 5:
If we divide 9 by 199, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 410.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 199

Let's proceed to step 6:
If we divide 98 by 199, we get 0 and a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 4100.0
Subtract 0 from 98 to get 98.
Bring next digit (9) of the dividend behind the 98 and repeat the process: 989 / 199

Let's proceed to step 7:
The number 199 fits into 989 4 times, leaving a remainder of 193.
Write down 4 as next digit of the result. 
Result so far: 41004.0
If we subtract 796 from 989, we get 193.
Append the next digit (3) from the dividend to 193 and continue with: 1933 / 199

Advancing to step 8:
The number 199 fits into 1933 9 times, leaving a remainder of 142.
The number 9 becomes the next digit in our result. 
Result so far: 410049.0
Subtracting 1791 from 1933 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 9:
When dividing 1420 by 199, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 410049.7
If we subtract 1393 from 1420, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
When dividing 270 by 199, we get 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 410049.71
Subtract 199 from 270 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 11:
710 divided by 199 is 3 with a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 410049.713
If we take 597 away from 710, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 12:
When dividing 1130 by 199, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 410049.7135
Deduct 995 from 1130 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 13:
1350 divided by 199 is 6 with a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 410049.71356
Subtract 1194 from 1350 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 14:
If we divide 1560 by 199, we get 7 and a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 410049.713567
If we take 1393 away from 1560, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 15:
199 goes into 1670 8 times with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 410049.7135678
If we take 1592 away from 1670, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 16:
199 can be fit into 780 3 times, resulting in a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 410049.71356783
Deduct 597 from 780 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Our division results in 410049.71356783 with a remaining 1.83e-07.
