We divide 86107781 by 844
We want to divide 86107781 by 844.

Moving on to step 1:
When dividing 8 by 844, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 844

Moving on to step 2:
86 divided by 844 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 844

Let's proceed to step 3:
The number 844 fits into 861 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 844 from 861 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 844

Going ahead to step 4:
If we divide 170 by 844, we get 0 and a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 170 after subtracting 0 from 170.
Grab the next digit (7) from the dividend, add it to 170, then carry on: 1707 / 844

Moving on to step 5:
When dividing 1707 by 844, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 1688 from 1707 leaves us with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 844

Moving on to step 6:
The number 844 fits into 197 0 times, leaving a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 1020.0
Deduct 0 from 197 and we're left with 197.
Grab the next digit (8) from the dividend, add it to 197, then carry on: 1978 / 844

Advancing to step 7:
The number 844 fits into 1978 2 times, leaving a remainder of 290.
Put 2 as the next digit of the answer. 
Result so far: 10202.0
Subtracting 1688 from 1978 leaves us with 290.
Fetch the next digit (1) from the dividend, attach it to 290 and continue: 2901 / 844

On to step 8:
If we divide 2901 by 844, we get 3 and a remainder of 369.
Write down 3 as next digit of the result. 
Result so far: 102023.0
Subtracting 2532 from 2901 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 9:
3690 divided by 844 is 4 with a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 102023.4
Deduct 3376 from 3690 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 10:
3140 divided by 844 is 3 with a remainder of 608.
Use 3 as the next digit of our solution. 
Result so far: 102023.43
If we subtract 2532 from 3140, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 11:
If we divide 6080 by 844, we get 7 and a remainder of 172.
The next digit of our result is 7. 
Result so far: 102023.437
Subtracting 5908 from 6080 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 12:
1720 divided by 844 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 102023.4372
Subtract 1688 from 1720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
If we divide 320 by 844, we get 0 and a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 102023.4372
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
The number 844 fits into 3200 3 times, leaving a remainder of 668.
Put 3 as the next digit of the answer. 
Result so far: 102023.437203
Deduct 2532 from 3200 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 15:
If we divide 6680 by 844, we get 7 and a remainder of 772.
The number 7 becomes the next digit in our result. 
Result so far: 102023.4372037
The remainder is 772 after subtracting 5908 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 16:
844 goes into 7720 9 times with a remainder of 124.
The number 9 becomes the next digit in our result. 
Result so far: 102023.43720379
Subtract 7596 from 7720 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 102023.43720379 with a remainder of 1.24e-07.
