We look at the division of 401774 by 91 
Our goal is to divide 401774 by 91.

Advancing to step 1:
91 goes into 4 0 times 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.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 91

Advancing to step 2:
91 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 91

Advancing to step 3:
The number 91 fits into 401 4 times, leaving a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 37 after subtracting 364 from 401.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 91

Let's proceed to step 4:
91 goes into 377 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 364 from 377, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 91

Advancing to step 5:
If we divide 137 by 91, we get 1 and a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 441.0
Subtract 91 from 137 to get 46.
Include the next digit (4) from the dividend after 46, then repeat: 464 / 91

Moving on to step 6:
If we divide 464 by 91, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 4415.0
Subtracting 455 from 464 leaves us with 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 7:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 4415.0
If we subtract 0 from 90, we 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.

Step 8:
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: 4415.09
If we take 819 away from 900, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
When dividing 810 by 91, we get 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 4415.098
The remainder is 82 after subtracting 728 from 810.
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 10:
If we divide 820 by 91, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4415.0989
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
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: 4415.0989
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
91 can be fit into 100 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4415.098901
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 4415.098901
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.

Advancing to step 14:
The number 91 fits into 900 9 times, leaving a remainder of 81.
The next digit of our result is 9. 
Result so far: 4415.09890109
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.

The quotient of the division is 4415.09890109, and the remainder is 8.1e-08.
