Let's divide 400274 by 99
We want to divide 400274 by 99.

On to step 1:
99 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.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 99

Step 2:
40 divided by 99 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 99

Let's proceed to step 3:
If we divide 400 by 99, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 396 away from 400, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 99

Going ahead to step 4:
99 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 99

On to step 5:
99 goes into 427 4 times with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Subtract 396 from 427 to get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 99

Let's proceed to step 6:
99 can be fit into 314 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 4043.0
The remainder is 17 after subtracting 297 from 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
99 goes into 170 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4043.1
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 8:
The number 99 fits into 710 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 4043.17
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
If we divide 170 by 99, we get 1 and a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 4043.171
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
If we divide 710 by 99, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 4043.1717
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
99 can be fit into 170 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 4043.17171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
99 can be fit into 710 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 4043.171717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
99 can be fit into 170 1 times, resulting in a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4043.1717171
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
If we divide 710 by 99, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 4043.17171717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 4043.17171717, with a leftover of 1.7e-08.
