89981393 ÷ 687 
Our goal is to divide 89981393 by 687.

Moving on to step 1:
687 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 687

Moving on to step 2:
687 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Take the next digit (9) from the dividend and append it to 89, then repeat: 899 / 687

Going ahead to step 3:
When dividing 899 by 687, we get 1 with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 687 away from 899, we end up with 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 687

Let's proceed to step 4:
When dividing 2128 by 687, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 2061 from 2128 to get 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 687

Let's proceed to step 5:
The number 687 fits into 671 0 times, leaving a remainder of 671.
Write down 0 as next digit of the result. 
Result so far: 130.0
If we subtract 0 from 671, we get 671.
Fetch the next digit (3) from the dividend, attach it to 671 and continue: 6713 / 687

Step 6:
When dividing 6713 by 687, we get 9 with a remainder of 530.
The next digit of our result is 9. 
Result so far: 1309.0
Subtracting 6183 from 6713 leaves us with 530.
Append the next digit (9) from the dividend to 530 and continue with: 5309 / 687

Going ahead to step 7:
If we divide 5309 by 687, we get 7 and a remainder of 500.
Write down 7 as next digit of the result. 
Result so far: 13097.0
If we subtract 4809 from 5309, we get 500.
Include the next digit (3) from the dividend after 500, then repeat: 5003 / 687

Moving on to step 8:
687 can be fit into 5003 7 times, resulting in a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 130977.0
The remainder is 194 after subtracting 4809 from 5003.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 9:
The number 687 fits into 1940 2 times, leaving a remainder of 566.
The number 2 becomes the next digit in our result. 
Result so far: 130977.2
Deduct 1374 from 1940 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 10:
When dividing 5660 by 687, we get 8 with a remainder of 164.
The next digit of our result is 8. 
Result so far: 130977.28
The remainder is 164 after subtracting 5496 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 11:
1640 divided by 687 is 2 with a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 130977.282
If we take 1374 away from 1640, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 12:
The number 687 fits into 2660 3 times, leaving a remainder of 599.
Use 3 as the next digit of our solution. 
Result so far: 130977.2823
The remainder is 599 after subtracting 2061 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Advancing to step 13:
687 can be fit into 5990 8 times, resulting in a remainder of 494.
The next digit of our result is 8. 
Result so far: 130977.28238
If we subtract 5496 from 5990, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 14:
When dividing 4940 by 687, we get 7 with a remainder of 131.
The number 7 becomes the next digit in our result. 
Result so far: 130977.282387
The remainder is 131 after subtracting 4809 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 15:
687 goes into 1310 1 times with a remainder of 623.
Write down 1 as next digit of the result. 
Result so far: 130977.2823871
Subtracting 687 from 1310 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 16:
6230 divided by 687 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 130977.28238719
The remainder is 47 after subtracting 6183 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

In conclusion, the division gives 130977.28238719 with a balance of 4.7e-08.
