We're dividing 729640 by 91 
We want to figure out the number of times 729640 can be divided by 91.

Advancing to step 1:
7 divided by 91 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 91

Step 2:
91 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 91

Advancing to step 3:
If we divide 729 by 91, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 728 from 729 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 91

On to step 4:
91 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 16, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 91

Let's proceed to step 5:
When dividing 164 by 91, we get 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 801.0
Subtract 91 from 164 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 91

Going ahead to step 6:
91 goes into 730 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8018.0
If we take 728 away from 730, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 91, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8018.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 91 fits into 200 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8018.02
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
91 goes into 180 1 times with a remainder of 89.
The next digit of our result is 1. 
Result so far: 8018.021
Subtract 91 from 180 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 10:
When dividing 890 by 91, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 8018.0219
If we take 819 away from 890, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 11:
91 goes into 710 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 8018.02197
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 12:
91 goes into 730 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8018.021978
Subtract 728 from 730 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
91 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8018.021978
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
The number 91 fits into 200 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 8018.02197802
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 8018.02197802 with a remainder of 1.8e-08.
