We're dividing 161304 by 74 
The aim is to understand the frequency of 74 in 161304.

On to step 1:
1 divided by 74 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 74

On to step 2:
16 divided by 74 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 74

On to step 3:
161 divided by 74 is 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 13 after subtracting 148 from 161.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 74

Step 4:
If we divide 133 by 74, we get 1 and a remainder of 59.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 59 after subtracting 74 from 133.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 74

Let's proceed to step 5:
74 goes into 590 7 times with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
Subtract 518 from 590 to get 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 74

Let's proceed to step 6:
74 can be fit into 724 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 2179.0
Subtracting 666 from 724 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
74 can be fit into 580 7 times, resulting in a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 2179.7
If we take 518 away from 580, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
The number 74 fits into 620 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 2179.78
Subtracting 592 from 620 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 74 is 3 with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 2179.783
If we subtract 222 from 280, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
74 can be fit into 580 7 times, resulting in a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 2179.7837
If we take 518 away from 580, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
74 goes into 620 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 2179.78378
The remainder is 28 after subtracting 592 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
If we divide 280 by 74, we get 3 and a remainder of 58.
The next digit of our result is 3. 
Result so far: 2179.783783
Subtract 222 from 280 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
If we divide 580 by 74, we get 7 and a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 2179.7837837
Deduct 518 from 580 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 74, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 2179.78378378
Subtract 592 from 620 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 2179.78378378, and the remainder is 2.8e-08.
