We look at the division of 47718628 by 325 
The aim is to understand the frequency of 325 in 47718628.

On to step 1:
325 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 325

Let's proceed to step 2:
325 can be fit into 47 0 times, resulting in a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 325

On to step 3:
477 divided by 325 is 1 with a remainder of 152.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 325 from 477 and we're left with 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 325

Going ahead to step 4:
1521 divided by 325 is 4 with a remainder of 221.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 221 after subtracting 1300 from 1521.
Include the next digit (8) from the dividend after 221, then repeat: 2218 / 325

Going ahead to step 5:
2218 divided by 325 is 6 with a remainder of 268.
The next digit of our result is 6. 
Result so far: 146.0
Subtracting 1950 from 2218 leaves us with 268.
Fetch the next digit (6) from the dividend, attach it to 268 and continue: 2686 / 325

Step 6:
325 goes into 2686 8 times with a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 1468.0
If we subtract 2600 from 2686, we get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 325

Going ahead to step 7:
If we divide 862 by 325, we get 2 and a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 14682.0
Subtracting 650 from 862 leaves us with 212.
Grab the next digit (8) from the dividend, add it to 212, then carry on: 2128 / 325

Step 8:
When dividing 2128 by 325, we get 6 with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 146826.0
Deduct 1950 from 2128 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
1780 divided by 325 is 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 146826.5
Deduct 1625 from 1780 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 10:
If we divide 1550 by 325, we get 4 and a remainder of 250.
Put 4 as the next digit of the answer. 
Result so far: 146826.54
Deduct 1300 from 1550 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.

Advancing to step 11:
If we divide 2500 by 325, we get 7 and a remainder of 225.
The next digit of our result is 7. 
Result so far: 146826.547
Subtract 2275 from 2500 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 12:
The number 325 fits into 2250 6 times, leaving a remainder of 300.
The number 6 becomes the next digit in our result. 
Result so far: 146826.5476
If we subtract 1950 from 2250, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 13:
3000 divided by 325 is 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 146826.54769
Subtract 2925 from 3000 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
When dividing 750 by 325, we get 2 with a remainder of 100.
The next digit of our result is 2. 
Result so far: 146826.547692
The remainder is 100 after subtracting 650 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
If we divide 1000 by 325, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 146826.5476923
Deduct 975 from 1000 and we're left 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.

Step 16:
If we divide 250 by 325, we get 0 and a remainder of 250.
The next digit of our result is 0. 
Result so far: 146826.5476923
Subtract 0 from 250 to 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 result is 146826.5476923 with a remainder of 2.5e-07.
