We look at the division of 449983 by 91 
We want to figure out the number of times 449983 can be divided by 91.

On to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 91

On to step 2:
If we divide 44 by 91, we get 0 and a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 91

Let's proceed to step 3:
The number 91 fits into 449 4 times, leaving a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 85 after subtracting 364 from 449.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 91

Going ahead to step 4:
When dividing 859 by 91, we get 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 819 from 859 leaves us with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 91

Advancing to step 5:
The number 91 fits into 408 4 times, leaving a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 494.0
Subtract 364 from 408 to get 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 91

Advancing to step 6:
443 divided by 91 is 4 with a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 4944.0
If we take 364 away from 443, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
The number 91 fits into 790 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 4944.8
The remainder is 62 after subtracting 728 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 91, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 4944.86
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
91 goes into 740 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4944.868
If we subtract 728 from 740, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
If we divide 120 by 91, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4944.8681
Subtracting 91 from 120 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
91 can be fit into 290 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 4944.86813
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
170 divided by 91 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 4944.868131
Deduct 91 from 170 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 13:
91 can be fit into 790 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 4944.8681318
The remainder is 62 after subtracting 728 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 91, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 4944.86813186
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 4944.86813186, and the remainder is 7.4e-08.
