4748829 ÷ 231 
The aim is to understand the frequency of 231 in 4748829.

Let's proceed to step 1:
When dividing 4 by 231, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 231

On to step 2:
231 goes into 47 0 times with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 231

Moving on to step 3:
474 divided by 231 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 462 from 474 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 231

Let's proceed to step 4:
The number 231 fits into 128 0 times, leaving a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 128, we get 128.
Fetch the next digit (8) from the dividend, attach it to 128 and continue: 1288 / 231

Step 5:
When dividing 1288 by 231, we get 5 with a remainder of 133.
Put 5 as the next digit of the answer. 
Result so far: 205.0
Subtracting 1155 from 1288 leaves us with 133.
Grab the next digit (2) from the dividend, add it to 133, then carry on: 1332 / 231

On to step 6:
231 goes into 1332 5 times with a remainder of 177.
Write down 5 as next digit of the result. 
Result so far: 2055.0
If we take 1155 away from 1332, we end up with 177.
Fetch the next digit (9) from the dividend, attach it to 177 and continue: 1779 / 231

Going ahead to step 7:
231 goes into 1779 7 times with a remainder of 162.
Write down 7 as next digit of the result. 
Result so far: 20557.0
The remainder is 162 after subtracting 1617 from 1779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 8:
When dividing 1620 by 231, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 20557.7
If we take 1617 away from 1620, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 231, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 20557.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
231 can be fit into 300 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 20557.701
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
231 can be fit into 690 2 times, resulting in a remainder of 228.
Write down 2 as next digit of the result. 
Result so far: 20557.7012
Subtracting 462 from 690 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 12:
231 goes into 2280 9 times with a remainder of 201.
Put 9 as the next digit of the answer. 
Result so far: 20557.70129
Deduct 2079 from 2280 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 13:
If we divide 2010 by 231, we get 8 and a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 20557.701298
Subtract 1848 from 2010 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 14:
If we divide 1620 by 231, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 20557.7012987
The remainder is 3 after subtracting 1617 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 15:
If we divide 30 by 231, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 20557.7012987
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 20557.7012987 with a balance of 3e-08.
