87639842 ÷ 925 
Let's see how many times 925 fits into 87639842.

On to step 1:
The number 925 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 925

On to step 2:
If we divide 87 by 925, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 925

Moving on to step 3:
If we divide 876 by 925, we get 0 and a remainder of 876.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 876 to get 876.
Include the next digit (3) from the dividend after 876, then repeat: 8763 / 925

Moving on to step 4:
925 goes into 8763 9 times with a remainder of 438.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 8325 from 8763, we get 438.
Grab the next digit (9) from the dividend, add it to 438, then carry on: 4389 / 925

On to step 5:
925 can be fit into 4389 4 times, resulting in a remainder of 689.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 3700 from 4389 leaves us with 689.
Append the next digit (8) from the dividend to 689 and continue with: 6898 / 925

On to step 6:
925 goes into 6898 7 times with a remainder of 423.
Write down 7 as next digit of the result. 
Result so far: 947.0
Subtract 6475 from 6898 to get 423.
Append the next digit (4) from the dividend to 423 and continue with: 4234 / 925

On to step 7:
925 can be fit into 4234 4 times, resulting in a remainder of 534.
Record the quotient 4 as the next digit in the result. 
Result so far: 9474.0
If we take 3700 away from 4234, we end up with 534.
Append the next digit (2) from the dividend to 534 and continue with: 5342 / 925

Moving on to step 8:
925 can be fit into 5342 5 times, resulting in a remainder of 717.
The next digit of our result is 5. 
Result so far: 94745.0
If we take 4625 away from 5342, we end up with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Going ahead to step 9:
When dividing 7170 by 925, we get 7 with a remainder of 695.
Record the quotient 7 as the next digit in the result. 
Result so far: 94745.7
Subtract 6475 from 7170 to get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Let's proceed to step 10:
925 can be fit into 6950 7 times, resulting in a remainder of 475.
Record the quotient 7 as the next digit in the result. 
Result so far: 94745.77
Subtracting 6475 from 6950 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The quotient of the division is 94745.77, and the remainder is 0.475.
