We look at the division of 397547 by 91 
We want to divide 397547 by 91.

Let's proceed to step 1:
3 divided by 91 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 91

Step 2:
39 divided by 91 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 91

Advancing to step 3:
397 divided by 91 is 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 364 from 397, we get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 91

Advancing to step 4:
91 goes into 335 3 times with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 273 from 335 leaves us with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 91

Advancing to step 5:
91 can be fit into 624 6 times, resulting in a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 436.0
If we subtract 546 from 624, we get 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 91

On to step 6:
91 goes into 787 8 times with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 4368.0
Deduct 728 from 787 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
590 divided by 91 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 4368.6
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
440 divided by 91 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4368.64
Subtracting 364 from 440 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
91 goes into 760 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4368.648
Subtract 728 from 760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4368.6483
Deduct 273 from 320 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
91 can be fit into 470 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4368.64835
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
91 goes into 150 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 4368.648351
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 13:
91 can be fit into 590 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 4368.6483516
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
When dividing 440 by 91, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 4368.64835164
Subtracting 364 from 440 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 4368.64835164 with a remainder of 7.6e-08.
