Let's divide 91887538 by 869
We want to figure out the number of times 91887538 can be divided by 869.

On to step 1:
869 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 869

Moving on to step 2:
If we divide 91 by 869, we get 0 and a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 869

Moving on to step 3:
If we divide 918 by 869, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 869 from 918 and we're left with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 869

Going ahead to step 4:
498 divided by 869 is 0 with a remainder of 498.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 498 after subtracting 0 from 498.
Take the next digit (7) from the dividend and append it to 498, then repeat: 4987 / 869

Going ahead to step 5:
869 can be fit into 4987 5 times, resulting in a remainder of 642.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 4345 away from 4987, we end up with 642.
Fetch the next digit (5) from the dividend, attach it to 642 and continue: 6425 / 869

On to step 6:
6425 divided by 869 is 7 with a remainder of 342.
The next digit of our result is 7. 
Result so far: 1057.0
Subtract 6083 from 6425 to get 342.
Bring next digit (3) of the dividend behind the 342 and repeat the process: 3423 / 869

Step 7:
869 goes into 3423 3 times with a remainder of 816.
The next digit of our result is 3. 
Result so far: 10573.0
If we take 2607 away from 3423, we end up with 816.
Include the next digit (8) from the dividend after 816, then repeat: 8168 / 869

On to step 8:
If we divide 8168 by 869, we get 9 and a remainder of 347.
Record the quotient 9 as the next digit in the result. 
Result so far: 105739.0
If we take 7821 away from 8168, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 9:
869 can be fit into 3470 3 times, resulting in a remainder of 863.
Write down 3 as next digit of the result. 
Result so far: 105739.3
Subtract 2607 from 3470 to get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Step 10:
869 can be fit into 8630 9 times, resulting in a remainder of 809.
Use 9 as the next digit of our solution. 
Result so far: 105739.39
The remainder is 809 after subtracting 7821 from 8630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Advancing to step 11:
869 can be fit into 8090 9 times, resulting in a remainder of 269.
The next digit of our result is 9. 
Result so far: 105739.399
Deduct 7821 from 8090 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The quotient of the division is 105739.399, and the remainder is 0.0269.
