We divide 408599 by 91
We want to divide 408599 by 91.

Let's proceed to step 1:
91 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 91

Let's proceed to step 2:
91 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 91

Step 3:
91 can be fit into 408 4 times, resulting in a remainder of 44.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 364 from 408, we get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 91

Moving on to step 4:
445 divided by 91 is 4 with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 364 from 445 leaves us with 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 91

Advancing to step 5:
If we divide 819 by 91, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 449.0
If we subtract 819 from 819, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 91

Step 6:
When dividing 9 by 91, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 4490.0
If we take 0 away from 9, we end up 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:
90 divided by 91 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 4490.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
If we divide 900 by 91, we get 9 and a remainder of 81.
The next digit of our result is 9. 
Result so far: 4490.09
Subtracting 819 from 900 leaves us 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.

Moving on to step 9:
91 goes into 810 8 times with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 4490.098
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.

Moving on to step 10:
When dividing 820 by 91, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4490.0989
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 11:
When dividing 10 by 91, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4490.0989
Deduct 0 from 10 and we're left 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.

Let's proceed to step 12:
91 goes into 100 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 4490.098901
Subtract 91 from 100 to 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.

Step 13:
If we divide 90 by 91, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 4490.098901
Deduct 0 from 90 and we're left with 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.
Put 9 as the next digit of the answer. 
Result so far: 4490.09890109
Deduct 819 from 900 and we're left 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.

The final outcome is 4490.09890109, with a leftover of 8.1e-08.
