We look at the division of 90261139 by 861 
We want to divide 90261139 by 861.

Advancing to step 1:
861 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 861

Moving on to step 2:
If we divide 90 by 861, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 861

Advancing to step 3:
The number 861 fits into 902 1 times, leaving a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 861 from 902 to get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 861

Advancing to step 4:
861 can be fit into 416 0 times, resulting in a remainder of 416.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 416 after subtracting 0 from 416.
Grab the next digit (1) from the dividend, add it to 416, then carry on: 4161 / 861

Advancing to step 5:
4161 divided by 861 is 4 with a remainder of 717.
The next digit of our result is 4. 
Result so far: 104.0
The remainder is 717 after subtracting 3444 from 4161.
Grab the next digit (1) from the dividend, add it to 717, then carry on: 7171 / 861

Going ahead to step 6:
7171 divided by 861 is 8 with a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 1048.0
Deduct 6888 from 7171 and we're left with 283.
Fetch the next digit (3) from the dividend, attach it to 283 and continue: 2833 / 861

Moving on to step 7:
If we divide 2833 by 861, we get 3 and a remainder of 250.
Record the quotient 3 as the next digit in the result. 
Result so far: 10483.0
If we subtract 2583 from 2833, we get 250.
Append the next digit (9) from the dividend to 250 and continue with: 2509 / 861

Moving on to step 8:
If we divide 2509 by 861, we get 2 and a remainder of 787.
Record the quotient 2 as the next digit in the result. 
Result so far: 104832.0
The remainder is 787 after subtracting 1722 from 2509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Moving on to step 9:
7870 divided by 861 is 9 with a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 104832.9
If we take 7749 away from 7870, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 10:
If we divide 1210 by 861, we get 1 and a remainder of 349.
The number 1 becomes the next digit in our result. 
Result so far: 104832.91
Deduct 861 from 1210 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 11:
3490 divided by 861 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 104832.914
Subtracting 3444 from 3490 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
The number 861 fits into 460 0 times, leaving a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 104832.914
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 13:
4600 divided by 861 is 5 with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 104832.91405
If we take 4305 away from 4600, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 14:
861 can be fit into 2950 3 times, resulting in a remainder of 367.
Write down 3 as next digit of the result. 
Result so far: 104832.914053
If we take 2583 away from 2950, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 15:
When dividing 3670 by 861, we get 4 with a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 104832.9140534
Subtract 3444 from 3670 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 16:
2260 divided by 861 is 2 with a remainder of 538.
Record the quotient 2 as the next digit in the result. 
Result so far: 104832.91405342
Subtracting 1722 from 2260 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 104832.91405342, and the remainder is 5.38e-07.
