We divide 400136 by 91
We're looking to find how many times 91 goes into 400136.

Step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 91

Going ahead to step 2:
The number 91 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 91

Let's proceed to step 3:
When dividing 400 by 91, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 364 from 400, we get 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 91

Advancing to step 4:
When dividing 361 by 91, we get 3 with a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 273 away from 361, we end up with 88.
Grab the next digit (3) from the dividend, add it to 88, then carry on: 883 / 91

Going ahead to step 5:
91 can be fit into 883 9 times, resulting in a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 439.0
If we subtract 819 from 883, we get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 91

Going ahead to step 6:
91 can be fit into 646 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 4397.0
Deduct 637 from 646 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 7:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 4397.0
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:
91 can be fit into 900 9 times, resulting in a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 4397.09
The remainder is 81 after subtracting 819 from 900.
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:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 4397.098
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
820 divided by 91 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 4397.0989
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.

On to step 11:
If we divide 10 by 91, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4397.0989
If we subtract 0 from 10, we get 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 next digit of our result is 1. 
Result so far: 4397.098901
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
91 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 4397.098901
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 14:
900 divided by 91 is 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 4397.09890109
If we subtract 819 from 900, we 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.

After the division, we end up with 4397.09890109 and a remainder of 8.1e-08.
