Let's divide 68012637 by 91
Our goal is to divide 68012637 by 91.

Advancing to step 1:
When dividing 6 by 91, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 91

Moving on to step 2:
The number 91 fits into 68 0 times, leaving a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 91

Step 3:
The number 91 fits into 680 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 637 from 680 leaves us with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 91

Moving on to step 4:
If we divide 431 by 91, we get 4 and a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 364 from 431, we get 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 91

Let's proceed to step 5:
672 divided by 91 is 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 747.0
If we take 637 away from 672, we end up with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 91

Let's proceed to step 6:
91 goes into 356 3 times with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 7473.0
Subtracting 273 from 356 leaves us with 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 91

On to step 7:
91 goes into 833 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 74739.0
Subtract 819 from 833 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 91

Advancing to step 8:
The number 91 fits into 147 1 times, leaving a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 747391.0
If we take 91 away from 147, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
91 can be fit into 560 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 747391.6
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 91 fits into 140 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 747391.61
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
490 divided by 91 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 747391.615
Deduct 455 from 490 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
When dividing 350 by 91, we get 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 747391.6153
Subtract 273 from 350 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 13:
When dividing 770 by 91, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 747391.61538
Subtracting 728 from 770 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
91 goes into 420 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 747391.615384
If we subtract 364 from 420, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
91 goes into 560 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 747391.6153846
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 16:
91 can be fit into 140 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 747391.61538461
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 747391.61538461, with a leftover of 4.9e-08.
