We divide 23157448 by 315
The aim is to understand the frequency of 315 in 23157448.

On to step 1:
2 divided by 315 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 315

Step 2:
When dividing 23 by 315, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 315

Advancing to step 3:
When dividing 231 by 315, we get 0 with a remainder of 231.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 231 and we're left with 231.
Grab the next digit (5) from the dividend, add it to 231, then carry on: 2315 / 315

Step 4:
If we divide 2315 by 315, we get 7 and a remainder of 110.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2205 from 2315 and we're left with 110.
Grab the next digit (7) from the dividend, add it to 110, then carry on: 1107 / 315

Step 5:
If we divide 1107 by 315, we get 3 and a remainder of 162.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 945 from 1107 leaves us with 162.
Append the next digit (4) from the dividend to 162 and continue with: 1624 / 315

On to step 6:
1624 divided by 315 is 5 with a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 735.0
The remainder is 49 after subtracting 1575 from 1624.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 315

Going ahead to step 7:
315 goes into 494 1 times with a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 7351.0
If we take 315 away from 494, we end up with 179.
Grab the next digit (8) from the dividend, add it to 179, then carry on: 1798 / 315

On to step 8:
The number 315 fits into 1798 5 times, leaving a remainder of 223.
The next digit of our result is 5. 
Result so far: 73515.0
The remainder is 223 after subtracting 1575 from 1798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 9:
315 goes into 2230 7 times with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 73515.7
If we take 2205 away from 2230, we end up 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.

On to step 10:
The number 315 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 73515.7
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
315 can be fit into 2500 7 times, resulting in a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 73515.707
If we subtract 2205 from 2500, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 12:
The number 315 fits into 2950 9 times, leaving a remainder of 115.
The next digit of our result is 9. 
Result so far: 73515.7079
Subtract 2835 from 2950 to 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.

Going ahead to step 13:
The number 315 fits into 1150 3 times, leaving a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 73515.70793
The remainder is 205 after subtracting 945 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 14:
2050 divided by 315 is 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 73515.707936
If we subtract 1890 from 2050, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
1600 divided by 315 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 73515.7079365
If we subtract 1575 from 1600, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 16:
The number 315 fits into 250 0 times, leaving a remainder of 250.
The next digit of our result is 0. 
Result so far: 73515.7079365
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 73515.7079365, with a leftover of 2.5e-07.
