We divide 52431017 by 987
We want to figure out the number of times 52431017 can be divided by 987.

Moving on to step 1:
The number 987 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 987

Advancing to step 2:
When dividing 52 by 987, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 987

Step 3:
The number 987 fits into 524 0 times, leaving a remainder of 524.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 524, we get 524.
Bring next digit (3) of the dividend behind the 524 and repeat the process: 5243 / 987

Moving on to step 4:
If we divide 5243 by 987, we get 5 and a remainder of 308.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4935 from 5243, we get 308.
Grab the next digit (1) from the dividend, add it to 308, then carry on: 3081 / 987

On to step 5:
987 goes into 3081 3 times with a remainder of 120.
The next digit of our result is 3. 
Result so far: 53.0
If we take 2961 away from 3081, we end up with 120.
Include the next digit (0) from the dividend after 120, then repeat: 1200 / 987

Advancing to step 6:
When dividing 1200 by 987, we get 1 with a remainder of 213.
Write down 1 as next digit of the result. 
Result so far: 531.0
Subtract 987 from 1200 to get 213.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 987

Advancing to step 7:
2131 divided by 987 is 2 with a remainder of 157.
Write down 2 as next digit of the result. 
Result so far: 5312.0
If we take 1974 away from 2131, we end up with 157.
Grab the next digit (7) from the dividend, add it to 157, then carry on: 1577 / 987

Going ahead to step 8:
When dividing 1577 by 987, we get 1 with a remainder of 590.
Write down 1 as next digit of the result. 
Result so far: 53121.0
Subtract 987 from 1577 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 9:
987 can be fit into 5900 5 times, resulting in a remainder of 965.
Record the quotient 5 as the next digit in the result. 
Result so far: 53121.5
Subtracting 4935 from 5900 leaves us with 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

On to step 10:
9650 divided by 987 is 9 with a remainder of 767.
Put 9 as the next digit of the answer. 
Result so far: 53121.59
Deduct 8883 from 9650 and we're left with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Moving on to step 11:
7670 divided by 987 is 7 with a remainder of 761.
Use 7 as the next digit of our solution. 
Result so far: 53121.597
Subtract 6909 from 7670 to get 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

On to step 12:
987 can be fit into 7610 7 times, resulting in a remainder of 701.
The next digit of our result is 7. 
Result so far: 53121.5977
Subtract 6909 from 7610 to get 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

The quotient of the division is 53121.5977, and the remainder is 0.00701.
