We're dividing 86255578 by 691 
Let's see how many times 691 fits into 86255578.

Going ahead to step 1:
The number 691 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 691

Going ahead to step 2:
691 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 691

Going ahead to step 3:
If we divide 862 by 691, we get 1 and a remainder of 171.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 171 after subtracting 691 from 862.
Append the next digit (5) from the dividend to 171 and continue with: 1715 / 691

Step 4:
691 can be fit into 1715 2 times, resulting in a remainder of 333.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1382 from 1715 and we're left with 333.
Append the next digit (5) from the dividend to 333 and continue with: 3335 / 691

Step 5:
3335 divided by 691 is 4 with a remainder of 571.
The next digit of our result is 4. 
Result so far: 124.0
Deduct 2764 from 3335 and we're left with 571.
Take the next digit (5) from the dividend and append it to 571, then repeat: 5715 / 691

Step 6:
691 goes into 5715 8 times with a remainder of 187.
Use 8 as the next digit of our solution. 
Result so far: 1248.0
If we subtract 5528 from 5715, we get 187.
Bring next digit (7) of the dividend behind the 187 and repeat the process: 1877 / 691

Step 7:
691 goes into 1877 2 times with a remainder of 495.
The number 2 becomes the next digit in our result. 
Result so far: 12482.0
If we take 1382 away from 1877, we end up with 495.
Append the next digit (8) from the dividend to 495 and continue with: 4958 / 691

Advancing to step 8:
691 goes into 4958 7 times with a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 124827.0
Subtract 4837 from 4958 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
When dividing 1210 by 691, we get 1 with a remainder of 519.
Put 1 as the next digit of the answer. 
Result so far: 124827.1
Deduct 691 from 1210 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 10:
If we divide 5190 by 691, we get 7 and a remainder of 353.
Write down 7 as next digit of the result. 
Result so far: 124827.17
The remainder is 353 after subtracting 4837 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 11:
691 can be fit into 3530 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 124827.175
The remainder is 75 after subtracting 3455 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
When dividing 750 by 691, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 124827.1751
Subtract 691 from 750 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 13:
691 can be fit into 590 0 times, resulting in a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 124827.1751
Subtracting 0 from 590 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 14:
The number 691 fits into 5900 8 times, leaving a remainder of 372.
Record the quotient 8 as the next digit in the result. 
Result so far: 124827.175108
Deduct 5528 from 5900 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 15:
The number 691 fits into 3720 5 times, leaving a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 124827.1751085
If we take 3455 away from 3720, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 16:
When dividing 2650 by 691, we get 3 with a remainder of 577.
The next digit of our result is 3. 
Result so far: 124827.17510853
If we take 2073 away from 2650, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

After the division, we end up with 124827.17510853 and a remainder of 5.77e-07.
