We're dividing 424159 by 91 
We want to divide 424159 by 91.

Going ahead to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 91

Advancing to step 2:
42 divided by 91 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 91

Step 3:
When dividing 424 by 91, we get 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 364 from 424 to get 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 91

On to step 4:
91 can be fit into 601 6 times, resulting in a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 546 from 601, we get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 91

On to step 5:
If we divide 555 by 91, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 466.0
Subtracting 546 from 555 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 91

Advancing to step 6:
91 can be fit into 99 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 4661.0
If we subtract 91 from 99, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 91 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4661.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
When dividing 800 by 91, we get 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 4661.08
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
If we divide 720 by 91, we get 7 and a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 4661.087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 10:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 4661.0879
Deduct 819 from 830 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
91 goes into 110 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4661.08791
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
The number 91 fits into 190 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4661.087912
If we subtract 182 from 190, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 91 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 4661.087912
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
The number 91 fits into 800 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 4661.08791208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 4661.08791208 and a remainder of 7.2e-08.
