Let's divide 70921879 by 91
We want to divide 70921879 by 91.

Step 1:
If we divide 7 by 91, we get 0 and 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 (0) from the dividend and append it to 7, then repeat: 70 / 91

Going ahead to step 2:
The number 91 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 91

On to step 3:
91 goes into 709 7 times with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 637 from 709 leaves us with 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 91

Step 4:
722 divided by 91 is 7 with a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 637 from 722 leaves us with 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 91

Advancing to step 5:
The number 91 fits into 851 9 times, leaving a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 779.0
The remainder is 32 after subtracting 819 from 851.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 91

Step 6:
91 can be fit into 328 3 times, resulting in a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 7793.0
If we take 273 away from 328, we end up with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 91

Step 7:
If we divide 557 by 91, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 77936.0
Subtract 546 from 557 to get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 91

Moving on to step 8:
91 can be fit into 119 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 779361.0
If we take 91 away from 119, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
When dividing 280 by 91, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 779361.3
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 779361.3
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
91 goes into 700 7 times with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 779361.307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
630 divided by 91 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 779361.3076
Subtract 546 from 630 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
When dividing 840 by 91, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 779361.30769
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
If we divide 210 by 91, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 779361.307692
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 15:
91 goes into 280 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 779361.3076923
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 779361.3076923
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 779361.3076923 and a remainder of 7e-08.
