Let's divide 74978474 by 315
The aim is to understand the frequency of 315 in 74978474.

Let's proceed to step 1:
315 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 315

Step 2:
If we divide 74 by 315, we get 0 and a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 315

On to step 3:
315 goes into 749 2 times with a remainder of 119.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 630 from 749, we get 119.
Fetch the next digit (7) from the dividend, attach it to 119 and continue: 1197 / 315

On to step 4:
When dividing 1197 by 315, we get 3 with a remainder of 252.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 945 from 1197 to get 252.
Take the next digit (8) from the dividend and append it to 252, then repeat: 2528 / 315

Let's proceed to step 5:
315 can be fit into 2528 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 238.0
Deduct 2520 from 2528 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 315

Moving on to step 6:
315 can be fit into 84 0 times, resulting in a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 2380.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 315

Moving on to step 7:
The number 315 fits into 847 2 times, leaving a remainder of 217.
The number 2 becomes the next digit in our result. 
Result so far: 23802.0
Subtracting 630 from 847 leaves us with 217.
Fetch the next digit (4) from the dividend, attach it to 217 and continue: 2174 / 315

On to step 8:
315 can be fit into 2174 6 times, resulting in a remainder of 284.
The next digit of our result is 6. 
Result so far: 238026.0
Deduct 1890 from 2174 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 9:
The number 315 fits into 2840 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 238026.9
Deduct 2835 from 2840 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 315, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 238026.9
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 315, we get 1 and a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 238026.901
Subtract 315 from 500 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 12:
1850 divided by 315 is 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 238026.9015
Subtract 1575 from 1850 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 13:
If we divide 2750 by 315, we get 8 and a remainder of 230.
Use 8 as the next digit of our solution. 
Result so far: 238026.90158
Subtracting 2520 from 2750 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
315 goes into 2300 7 times with a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 238026.901587
Deduct 2205 from 2300 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
The number 315 fits into 950 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 238026.9015873
If we subtract 945 from 950, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 16:
If we divide 50 by 315, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 238026.9015873
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 238026.9015873, and the remainder is 5e-08.
