We're dividing 40203034 by 231 
Our goal is to divide 40203034 by 231.

Moving on to step 1:
The number 231 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 231

Let's proceed to step 2:
When dividing 40 by 231, we get 0 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.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 231

Step 3:
The number 231 fits into 402 1 times, leaving a remainder of 171.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 231 from 402 leaves us with 171.
Include the next digit (0) from the dividend after 171, then repeat: 1710 / 231

Step 4:
1710 divided by 231 is 7 with a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 1617 from 1710, we get 93.
Bring next digit (3) of the dividend behind the 93 and repeat the process: 933 / 231

Advancing to step 5:
231 goes into 933 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 174.0
If we take 924 away from 933, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 231

Let's proceed to step 6:
If we divide 90 by 231, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 1740.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 231

On to step 7:
231 goes into 903 3 times with a remainder of 210.
Write down 3 as next digit of the result. 
Result so far: 17403.0
If we take 693 away from 903, we end up with 210.
Grab the next digit (4) from the dividend, add it to 210, then carry on: 2104 / 231

Going ahead to step 8:
The number 231 fits into 2104 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 174039.0
Deduct 2079 from 2104 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
231 can be fit into 250 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 174039.1
Deduct 231 from 250 and we're left 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.

Moving on to step 10:
The number 231 fits into 190 0 times, leaving a remainder of 190.
The next digit of our result is 0. 
Result so far: 174039.1
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
If we divide 1900 by 231, we get 8 and a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 174039.108
Subtracting 1848 from 1900 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
231 can be fit into 520 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 174039.1082
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
231 can be fit into 580 2 times, resulting in a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 174039.10822
If we take 462 away from 580, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 174039.10822, and the remainder is 0.000118.
