We look at the division of 673964 by 91 
We want to divide 673964 by 91.

Advancing to step 1:
6 divided by 91 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 91

Moving on to step 2:
67 divided by 91 is 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 91

Going ahead to step 3:
If we divide 673 by 91, we get 7 and a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 637 from 673 leaves us with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 91

Step 4:
369 divided by 91 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 364 from 369 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 91

On to step 5:
56 divided by 91 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 740.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 91

Step 6:
564 divided by 91 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 7406.0
The remainder is 18 after subtracting 546 from 564.
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 7:
When dividing 180 by 91, we get 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 7406.1
The remainder is 89 after subtracting 91 from 180.
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 8:
If we divide 890 by 91, we get 9 and a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 7406.19
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.

Let's proceed to step 9:
91 goes into 710 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 7406.197
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.

On to step 10:
The number 91 fits into 730 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 7406.1978
If we subtract 728 from 730, we 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 11:
If we divide 20 by 91, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7406.1978
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.

Advancing to step 12:
200 divided by 91 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 7406.197802
If we subtract 182 from 200, we get 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 13:
The number 91 fits into 180 1 times, leaving a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 7406.1978021
If we take 91 away from 180, we end up 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 14:
890 divided by 91 is 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 7406.19780219
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.

The final outcome is 7406.19780219, with a leftover of 7.1e-08.
