We divide 691137 by 86
We want to figure out the number of times 691137 can be divided by 86.

Moving on to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 86

Moving on to step 2:
69 divided by 86 is 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 86

Advancing to step 3:
691 divided by 86 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 688 from 691 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 86

Advancing to step 4:
If we divide 31 by 86, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 86

Going ahead to step 5:
If we divide 313 by 86, we get 3 and a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 803.0
If we subtract 258 from 313, we get 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 86

Advancing to step 6:
86 goes into 557 6 times with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 8036.0
The remainder is 41 after subtracting 516 from 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
86 goes into 410 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 8036.4
If we subtract 344 from 410, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 8036.47
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
86 goes into 580 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 8036.476
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
If we divide 640 by 86, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 8036.4767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
86 goes into 380 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 8036.47674
If we take 344 away from 380, we end up 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.

Going ahead to step 12:
If we divide 360 by 86, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 8036.476744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 8036.476744 with a remaining 1.6e-06.
