We're dividing 64478452 by 231 
We're looking to find how many times 231 goes into 64478452.

Step 1:
The number 231 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 231

Moving on to step 2:
The number 231 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 231

Moving on to step 3:
231 goes into 644 2 times with a remainder of 182.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 462 from 644, we get 182.
Take the next digit (7) from the dividend and append it to 182, then repeat: 1827 / 231

Advancing to step 4:
The number 231 fits into 1827 7 times, leaving a remainder of 210.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 1617 from 1827 to get 210.
Include the next digit (8) from the dividend after 210, then repeat: 2108 / 231

Let's proceed to step 5:
If we divide 2108 by 231, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 279.0
Subtracting 2079 from 2108 leaves us with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 231

Let's proceed to step 6:
If we divide 294 by 231, we get 1 and a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 2791.0
The remainder is 63 after subtracting 231 from 294.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 231

Moving on to step 7:
231 can be fit into 635 2 times, resulting in a remainder of 173.
Use 2 as the next digit of our solution. 
Result so far: 27912.0
Subtracting 462 from 635 leaves us with 173.
Grab the next digit (2) from the dividend, add it to 173, then carry on: 1732 / 231

Advancing to step 8:
231 can be fit into 1732 7 times, resulting in a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 279127.0
The remainder is 115 after subtracting 1617 from 1732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
The number 231 fits into 1150 4 times, leaving a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 279127.4
The remainder is 226 after subtracting 924 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
2260 divided by 231 is 9 with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 279127.49
Deduct 2079 from 2260 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 11:
When dividing 1810 by 231, we get 7 with a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 279127.497
If we subtract 1617 from 1810, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 12:
If we divide 1930 by 231, we get 8 and a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 279127.4978
If we take 1848 away from 1930, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 13:
231 can be fit into 820 3 times, resulting in a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 279127.49783
The remainder is 127 after subtracting 693 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 14:
231 can be fit into 1270 5 times, resulting in a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 279127.497835
If we subtract 1155 from 1270, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 15:
1150 divided by 231 is 4 with a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 279127.4978354
Subtracting 924 from 1150 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 16:
231 goes into 2260 9 times with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 279127.49783549
If we subtract 2079 from 2260, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Our division results in 279127.49783549 with a remaining 1.81e-07.
