87491080 divided by 647 
We want to figure out the number of times 87491080 can be divided by 647.

Going ahead to step 1:
647 goes into 8 0 times with 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.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 647

Advancing to step 2:
647 can be fit into 87 0 times, resulting in a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 647

On to step 3:
647 goes into 874 1 times with a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 227 after subtracting 647 from 874.
Fetch the next digit (9) from the dividend, attach it to 227 and continue: 2279 / 647

Advancing to step 4:
647 can be fit into 2279 3 times, resulting in a remainder of 338.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1941 from 2279 and we're left with 338.
Include the next digit (1) from the dividend after 338, then repeat: 3381 / 647

Let's proceed to step 5:
The number 647 fits into 3381 5 times, leaving a remainder of 146.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 3235 from 3381, we get 146.
Bring next digit (0) of the dividend behind the 146 and repeat the process: 1460 / 647

Moving on to step 6:
The number 647 fits into 1460 2 times, leaving a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 1352.0
Subtracting 1294 from 1460 leaves us with 166.
Include the next digit (8) from the dividend after 166, then repeat: 1668 / 647

On to step 7:
647 goes into 1668 2 times with a remainder of 374.
Put 2 as the next digit of the answer. 
Result so far: 13522.0
Deduct 1294 from 1668 and we're left with 374.
Grab the next digit (0) from the dividend, add it to 374, then carry on: 3740 / 647

Step 8:
The number 647 fits into 3740 5 times, leaving a remainder of 505.
Record the quotient 5 as the next digit in the result. 
Result so far: 135225.0
Subtracting 3235 from 3740 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 9:
If we divide 5050 by 647, we get 7 and a remainder of 521.
Write down 7 as next digit of the result. 
Result so far: 135225.7
If we take 4529 away from 5050, we end up with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 10:
The number 647 fits into 5210 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 135225.78
Deduct 5176 from 5210 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
When dividing 340 by 647, we get 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 135225.78
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 12:
If we divide 3400 by 647, we get 5 and a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 135225.7805
Deduct 3235 from 3400 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 13:
1650 divided by 647 is 2 with a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 135225.78052
The remainder is 356 after subtracting 1294 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 14:
When dividing 3560 by 647, we get 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 135225.780525
Subtract 3235 from 3560 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 15:
The number 647 fits into 3250 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 135225.7805255
Subtract 3235 from 3250 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 135225.7805255, and the remainder is 1.5e-07.
