Let's divide 89158255 by 686
We want to figure out the number of times 89158255 can be divided by 686.

On to step 1:
686 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 686

On to step 2:
If we divide 89 by 686, we get 0 and a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 686

Going ahead to step 3:
If we divide 891 by 686, we get 1 and a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 686 from 891 leaves us with 205.
Take the next digit (5) from the dividend and append it to 205, then repeat: 2055 / 686

Moving on to step 4:
686 goes into 2055 2 times with a remainder of 683.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1372 from 2055, we get 683.
Append the next digit (8) from the dividend to 683 and continue with: 6838 / 686

Let's proceed to step 5:
6838 divided by 686 is 9 with a remainder of 664.
The next digit of our result is 9. 
Result so far: 129.0
Deduct 6174 from 6838 and we're left with 664.
Fetch the next digit (2) from the dividend, attach it to 664 and continue: 6642 / 686

Advancing to step 6:
If we divide 6642 by 686, we get 9 and a remainder of 468.
Record the quotient 9 as the next digit in the result. 
Result so far: 1299.0
The remainder is 468 after subtracting 6174 from 6642.
Take the next digit (5) from the dividend and append it to 468, then repeat: 4685 / 686

On to step 7:
When dividing 4685 by 686, we get 6 with a remainder of 569.
The number 6 becomes the next digit in our result. 
Result so far: 12996.0
Subtracting 4116 from 4685 leaves us with 569.
Bring next digit (5) of the dividend behind the 569 and repeat the process: 5695 / 686

Advancing to step 8:
686 goes into 5695 8 times with a remainder of 207.
The number 8 becomes the next digit in our result. 
Result so far: 129968.0
The remainder is 207 after subtracting 5488 from 5695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 9:
686 goes into 2070 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 129968.3
Subtracting 2058 from 2070 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 686, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 129968.3
Subtracting 0 from 120 leaves us with 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 11:
When dividing 1200 by 686, we get 1 with a remainder of 514.
Put 1 as the next digit of the answer. 
Result so far: 129968.301
Deduct 686 from 1200 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 12:
686 goes into 5140 7 times with a remainder of 338.
The next digit of our result is 7. 
Result so far: 129968.3017
Deduct 4802 from 5140 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 13:
If we divide 3380 by 686, we get 4 and a remainder of 636.
Put 4 as the next digit of the answer. 
Result so far: 129968.30174
Subtracting 2744 from 3380 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 14:
The number 686 fits into 6360 9 times, leaving a remainder of 186.
Use 9 as the next digit of our solution. 
Result so far: 129968.301749
If we subtract 6174 from 6360, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 15:
686 can be fit into 1860 2 times, resulting in a remainder of 488.
Put 2 as the next digit of the answer. 
Result so far: 129968.3017492
Deduct 1372 from 1860 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 16:
If we divide 4880 by 686, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 129968.30174927
The remainder is 78 after subtracting 4802 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 129968.30174927 with a remaining 7.8e-08.
