We're dividing 73570432 by 231 
We want to divide 73570432 by 231.

Step 1:
7 divided by 231 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 231

On to step 2:
If we divide 73 by 231, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 231

Let's proceed to step 3:
231 can be fit into 735 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 42 after subtracting 693 from 735.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 231

Step 4:
The number 231 fits into 427 1 times, leaving a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 196 after subtracting 231 from 427.
Take the next digit (0) from the dividend and append it to 196, then repeat: 1960 / 231

On to step 5:
231 can be fit into 1960 8 times, resulting in a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 318.0
Subtracting 1848 from 1960 leaves us with 112.
Append the next digit (4) from the dividend to 112 and continue with: 1124 / 231

Moving on to step 6:
When dividing 1124 by 231, we get 4 with a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 3184.0
If we subtract 924 from 1124, we get 200.
Fetch the next digit (3) from the dividend, attach it to 200 and continue: 2003 / 231

Moving on to step 7:
2003 divided by 231 is 8 with a remainder of 155.
Use 8 as the next digit of our solution. 
Result so far: 31848.0
The remainder is 155 after subtracting 1848 from 2003.
Grab the next digit (2) from the dividend, add it to 155, then carry on: 1552 / 231

On to step 8:
The number 231 fits into 1552 6 times, leaving a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 318486.0
The remainder is 166 after subtracting 1386 from 1552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 9:
1660 divided by 231 is 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 318486.7
The remainder is 43 after subtracting 1617 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
When dividing 430 by 231, we get 1 with a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 318486.71
If we subtract 231 from 430, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 11:
The number 231 fits into 1990 8 times, leaving a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 318486.718
Subtracting 1848 from 1990 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 12:
The number 231 fits into 1420 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 318486.7186
If we subtract 1386 from 1420, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
The number 231 fits into 340 1 times, leaving a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 318486.71861
If we take 231 away from 340, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 14:
231 goes into 1090 4 times with a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 318486.718614
The remainder is 166 after subtracting 924 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 15:
When dividing 1660 by 231, we get 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 318486.7186147
The remainder is 43 after subtracting 1617 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 16:
231 goes into 430 1 times with a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 318486.71861471
Subtracting 231 from 430 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 318486.71861471 and a remainder of 1.99e-07.
