We look at the division of 458842 by 91 
We want to divide 458842 by 91.

Step 1:
91 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 91

Advancing to step 2:
When dividing 45 by 91, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 91

Advancing to step 3:
458 divided by 91 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 455 from 458 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 91

Advancing to step 4:
When dividing 38 by 91, we get 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 38 to get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 91

Let's proceed to step 5:
91 can be fit into 384 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 504.0
The remainder is 20 after subtracting 364 from 384.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 91

On to step 6:
When dividing 202 by 91, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 5042.0
If we subtract 182 from 202, we get 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 7:
91 goes into 200 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 5042.2
Deduct 182 from 200 and we're left with 18.
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 8:
180 divided by 91 is 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 5042.21
Subtract 91 from 180 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
If we divide 890 by 91, we get 9 and a remainder of 71.
The next digit of our result is 9. 
Result so far: 5042.219
Subtracting 819 from 890 leaves us 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.

Going ahead to step 10:
91 can be fit into 710 7 times, resulting in a remainder of 73.
The next digit of our result is 7. 
Result so far: 5042.2197
Subtracting 637 from 710 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
If we divide 730 by 91, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 5042.21978
Subtracting 728 from 730 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
91 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5042.21978
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.

On to step 13:
The number 91 fits into 200 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 5042.2197802
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
91 goes into 180 1 times with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 5042.21978021
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.

After the division, we end up with 5042.21978021 and a remainder of 8.9e-08.
