We look at the division of 445661 by 91 
Our goal is to divide 445661 by 91.

Let's proceed to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 91

Advancing to step 2:
The number 91 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 91

Step 3:
91 can be fit into 445 4 times, resulting in a remainder of 81.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 364 from 445 to get 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 91

Advancing to step 4:
When dividing 816 by 91, we get 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 728 from 816 to get 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 91

Step 5:
91 goes into 886 9 times with a remainder of 67.
The next digit of our result is 9. 
Result so far: 489.0
Subtract 819 from 886 to get 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 91

Step 6:
91 can be fit into 671 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4897.0
If we take 637 away from 671, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
When dividing 340 by 91, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 4897.3
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
If we divide 670 by 91, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 4897.37
Deduct 637 from 670 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
91 goes into 330 3 times with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 4897.373
Deduct 273 from 330 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
If we divide 570 by 91, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 4897.3736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
The number 91 fits into 240 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 4897.37362
Deduct 182 from 240 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
580 divided by 91 is 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 4897.373626
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
91 goes into 340 3 times with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 4897.3736263
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 14:
If we divide 670 by 91, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 4897.37362637
If we take 637 away from 670, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 4897.37362637 and a remainder of 3.3e-08.
