We look at the division of 78462582 by 921 
We want to divide 78462582 by 921.

Going ahead to step 1:
7 divided by 921 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 921

Going ahead to step 2:
The number 921 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 921

Moving on to step 3:
784 divided by 921 is 0 with a remainder of 784.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 784 after subtracting 0 from 784.
Include the next digit (6) from the dividend after 784, then repeat: 7846 / 921

On to step 4:
921 goes into 7846 8 times with a remainder of 478.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7368 from 7846 and we're left with 478.
Bring next digit (2) of the dividend behind the 478 and repeat the process: 4782 / 921

On to step 5:
921 can be fit into 4782 5 times, resulting in a remainder of 177.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 4605 from 4782 leaves us with 177.
Append the next digit (5) from the dividend to 177 and continue with: 1775 / 921

Let's proceed to step 6:
The number 921 fits into 1775 1 times, leaving a remainder of 854.
Put 1 as the next digit of the answer. 
Result so far: 851.0
Deduct 921 from 1775 and we're left with 854.
Grab the next digit (8) from the dividend, add it to 854, then carry on: 8548 / 921

Advancing to step 7:
The number 921 fits into 8548 9 times, leaving a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 8519.0
Deduct 8289 from 8548 and we're left with 259.
Grab the next digit (2) from the dividend, add it to 259, then carry on: 2592 / 921

On to step 8:
The number 921 fits into 2592 2 times, leaving a remainder of 750.
Write down 2 as next digit of the result. 
Result so far: 85192.0
The remainder is 750 after subtracting 1842 from 2592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 9:
When dividing 7500 by 921, we get 8 with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 85192.8
Subtract 7368 from 7500 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
The number 921 fits into 1320 1 times, leaving a remainder of 399.
Use 1 as the next digit of our solution. 
Result so far: 85192.81
Deduct 921 from 1320 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Going ahead to step 11:
3990 divided by 921 is 4 with a remainder of 306.
Record the quotient 4 as the next digit in the result. 
Result so far: 85192.814
Subtracting 3684 from 3990 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 12:
The number 921 fits into 3060 3 times, leaving a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 85192.8143
Deduct 2763 from 3060 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 13:
The number 921 fits into 2970 3 times, leaving a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 85192.81433
Subtract 2763 from 2970 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 85192.81433 and a remainder of 0.000207.
