We look at the division of 450168 by 91 
Our goal is to divide 450168 by 91.

Moving on to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 91

Moving on to step 2:
45 divided by 91 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 91

Advancing to step 3:
450 divided by 91 is 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 364 from 450, we get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 91

Step 4:
91 can be fit into 861 9 times, resulting in a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 819 from 861 to get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 91

On to step 5:
The number 91 fits into 426 4 times, leaving a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
The remainder is 62 after subtracting 364 from 426.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 91

Moving on to step 6:
When dividing 628 by 91, we get 6 with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 4946.0
Deduct 546 from 628 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
91 goes into 820 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4946.9
If we take 819 away from 820, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 91, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 4946.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 91 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4946.901
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
90 divided by 91 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 4946.901
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
If we divide 900 by 91, we get 9 and a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 4946.90109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 12:
If we divide 810 by 91, we get 8 and a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 4946.901098
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 13:
820 divided by 91 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4946.9010989
If we take 819 away from 820, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
If we divide 10 by 91, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4946.9010989
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4946.9010989, with a leftover of 1e-08.
