Let's divide 408673 by 91
Let's see how many times 91 fits into 408673.

On to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 91

On to step 2:
The number 91 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 91

Step 3:
When dividing 408 by 91, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 364 from 408 and we're left with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 91

Step 4:
When dividing 446 by 91, we get 4 with a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 364 away from 446, we end up with 82.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 91

On to step 5:
The number 91 fits into 827 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 449.0
If we subtract 819 from 827, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 91

On to step 6:
The number 91 fits into 83 0 times, leaving a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 4490.0
Subtracting 0 from 83 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
91 goes into 830 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4490.9
The remainder is 11 after subtracting 819 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
91 can be fit into 110 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 4490.91
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
91 can be fit into 190 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4490.912
Deduct 182 from 190 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
91 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4490.912
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
The number 91 fits into 800 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 4490.91208
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
91 goes into 720 7 times with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 4490.912087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 13:
If we divide 830 by 91, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 4490.9120879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
91 goes into 110 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4490.91208791
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 4490.91208791 with a remainder of 1.9e-08.
