86988648 ÷ 87 
Let's see how many times 87 fits into 86988648.

On to step 1:
87 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
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 87

Going ahead to step 2:
If we divide 86 by 87, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 87

Let's proceed to step 3:
The number 87 fits into 869 9 times, leaving a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 783 away from 869, we end up with 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 87

Advancing to step 4:
87 goes into 868 9 times with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtract 783 from 868 to get 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 87

Moving on to step 5:
If we divide 858 by 87, we get 9 and a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 999.0
Subtracting 783 from 858 leaves us with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 87

Let's proceed to step 6:
When dividing 756 by 87, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 9998.0
Subtract 696 from 756 to get 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 87

Step 7:
87 goes into 604 6 times with a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 99986.0
If we subtract 522 from 604, we get 82.
Bring next digit (8) of the dividend behind the 82 and repeat the process: 828 / 87

Going ahead to step 8:
The number 87 fits into 828 9 times, leaving a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 999869.0
If we subtract 783 from 828, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
When dividing 450 by 87, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 999869.5
Subtract 435 from 450 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.

Let's proceed to step 10:
87 can be fit into 150 1 times, resulting in a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 999869.51
If we subtract 87 from 150, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
If we divide 630 by 87, we get 7 and a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 999869.517
If we subtract 609 from 630, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
If we divide 210 by 87, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 999869.5172
Deduct 174 from 210 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
87 goes into 360 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 999869.51724
If we subtract 348 from 360, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
If we divide 120 by 87, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 999869.517241
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 15:
330 divided by 87 is 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 999869.5172413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 16:
When dividing 690 by 87, we get 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 999869.51724137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 999869.51724137, with a leftover of 8.1e-08.
