Let's divide 721355 by 91
Our goal is to divide 721355 by 91.

Going ahead to step 1:
91 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 91

Moving on to step 2:
72 divided by 91 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 91

On to step 3:
The number 91 fits into 721 7 times, leaving a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 637 from 721 to get 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 91

Going ahead to step 4:
If we divide 843 by 91, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 819 from 843 and we're left with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 91

Let's proceed to step 5:
91 can be fit into 245 2 times, resulting in a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 792.0
If we take 182 away from 245, we end up with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 91

Advancing to step 6:
91 can be fit into 635 6 times, resulting in a remainder of 89.
Record the quotient 6 as the next digit in the result. 
Result so far: 7926.0
If we subtract 546 from 635, we 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.

Step 7:
The number 91 fits into 890 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7926.9
The remainder is 71 after subtracting 819 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 8:
When dividing 710 by 91, we get 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 7926.97
If we take 637 away from 710, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
When dividing 730 by 91, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 7926.978
Subtracting 728 from 730 leaves us 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 10:
20 divided by 91 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7926.978
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
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: 7926.97802
Deduct 182 from 200 and we're left 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.

Let's proceed to step 12:
If we divide 180 by 91, we get 1 and a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 7926.978021
Deduct 91 from 180 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 13:
890 divided by 91 is 9 with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7926.9780219
Subtract 819 from 890 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
If we divide 710 by 91, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 7926.97802197
If we subtract 637 from 710, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 7926.97802197, with a leftover of 7.3e-08.
