91531336 divided by 715 
We want to figure out the number of times 91531336 can be divided by 715.

On to step 1:
The number 715 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 715

Step 2:
91 divided by 715 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 715

Moving on to step 3:
715 goes into 915 1 times with a remainder of 200.
The next digit of our result is 1. 
Result so far: 1.0
If we take 715 away from 915, we end up with 200.
Include the next digit (3) from the dividend after 200, then repeat: 2003 / 715

Step 4:
2003 divided by 715 is 2 with a remainder of 573.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1430 from 2003 and we're left with 573.
Append the next digit (1) from the dividend to 573 and continue with: 5731 / 715

Let's proceed to step 5:
The number 715 fits into 5731 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 5720 from 5731 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 715

Step 6:
715 can be fit into 113 0 times, resulting in a remainder of 113.
Record the quotient 0 as the next digit in the result. 
Result so far: 1280.0
Subtracting 0 from 113 leaves us with 113.
Fetch the next digit (3) from the dividend, attach it to 113 and continue: 1133 / 715

Advancing to step 7:
The number 715 fits into 1133 1 times, leaving a remainder of 418.
Record the quotient 1 as the next digit in the result. 
Result so far: 12801.0
If we subtract 715 from 1133, we get 418.
Grab the next digit (6) from the dividend, add it to 418, then carry on: 4186 / 715

Step 8:
If we divide 4186 by 715, we get 5 and a remainder of 611.
The number 5 becomes the next digit in our result. 
Result so far: 128015.0
If we take 3575 away from 4186, we end up with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

On to step 9:
When dividing 6110 by 715, we get 8 with a remainder of 390.
Write down 8 as next digit of the result. 
Result so far: 128015.8
Subtracting 5720 from 6110 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
If we divide 3900 by 715, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 128015.85
Subtract 3575 from 3900 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 11:
The number 715 fits into 3250 4 times, leaving a remainder of 390.
Put 4 as the next digit of the answer. 
Result so far: 128015.854
Subtract 2860 from 3250 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 12:
If we divide 3900 by 715, we get 5 and a remainder of 325.
The next digit of our result is 5. 
Result so far: 128015.8545
Subtracting 3575 from 3900 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 13:
If we divide 3250 by 715, we get 4 and a remainder of 390.
Use 4 as the next digit of our solution. 
Result so far: 128015.85454
If we subtract 2860 from 3250, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
If we divide 3900 by 715, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 128015.854545
Subtracting 3575 from 3900 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 15:
3250 divided by 715 is 4 with a remainder of 390.
The next digit of our result is 4. 
Result so far: 128015.8545454
The remainder is 390 after subtracting 2860 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 16:
If we divide 3900 by 715, we get 5 and a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 128015.85454545
Subtract 3575 from 3900 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Our division results in 128015.85454545 with a remaining 3.25e-07.
