87489810 ÷ 687 
We want to figure out the number of times 87489810 can be divided by 687.

Going ahead to step 1:
687 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 687

On to step 2:
If we divide 87 by 687, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 687

Advancing to step 3:
The number 687 fits into 874 1 times, leaving a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 687 from 874, we get 187.
Take the next digit (8) from the dividend and append it to 187, then repeat: 1878 / 687

Advancing to step 4:
1878 divided by 687 is 2 with a remainder of 504.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1374 from 1878 leaves us with 504.
Include the next digit (9) from the dividend after 504, then repeat: 5049 / 687

On to step 5:
The number 687 fits into 5049 7 times, leaving a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we take 4809 away from 5049, we end up with 240.
Append the next digit (8) from the dividend to 240 and continue with: 2408 / 687

Going ahead to step 6:
2408 divided by 687 is 3 with a remainder of 347.
The next digit of our result is 3. 
Result so far: 1273.0
If we take 2061 away from 2408, we end up with 347.
Append the next digit (1) from the dividend to 347 and continue with: 3471 / 687

Moving on to step 7:
687 can be fit into 3471 5 times, resulting in a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 12735.0
The remainder is 36 after subtracting 3435 from 3471.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 687

Advancing to step 8:
687 goes into 360 0 times with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 127350.0
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 9:
687 goes into 3600 5 times with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 127350.5
Deduct 3435 from 3600 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.

Let's proceed to step 10:
When dividing 1650 by 687, we get 2 with a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 127350.52
If we subtract 1374 from 1650, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
2760 divided by 687 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 127350.524
The remainder is 12 after subtracting 2748 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
The number 687 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 127350.524
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
If we divide 1200 by 687, we get 1 and a remainder of 513.
Use 1 as the next digit of our solution. 
Result so far: 127350.52401
If we subtract 687 from 1200, we get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 14:
5130 divided by 687 is 7 with a remainder of 321.
Put 7 as the next digit of the answer. 
Result so far: 127350.524017
If we subtract 4809 from 5130, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 15:
687 can be fit into 3210 4 times, resulting in a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 127350.5240174
Subtracting 2748 from 3210 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 16:
687 can be fit into 4620 6 times, resulting in a remainder of 498.
Put 6 as the next digit of the answer. 
Result so far: 127350.52401746
Subtracting 4122 from 4620 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

The quotient of the division is 127350.52401746, and the remainder is 4.98e-07.
