We're dividing 66685928 by 347 
The aim is to understand the frequency of 347 in 66685928.

Going ahead to step 1:
When dividing 6 by 347, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 347

Let's proceed to step 2:
347 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 347

Moving on to step 3:
666 divided by 347 is 1 with a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 347 from 666 to get 319.
Grab the next digit (8) from the dividend, add it to 319, then carry on: 3198 / 347

Step 4:
When dividing 3198 by 347, we get 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3123 from 3198 and we're left with 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 347

On to step 5:
347 goes into 755 2 times with a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 192.0
If we subtract 694 from 755, we get 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 347

On to step 6:
347 goes into 619 1 times with a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 1921.0
Subtract 347 from 619 to get 272.
Include the next digit (2) from the dividend after 272, then repeat: 2722 / 347

Moving on to step 7:
If we divide 2722 by 347, we get 7 and a remainder of 293.
The number 7 becomes the next digit in our result. 
Result so far: 19217.0
If we take 2429 away from 2722, we end up with 293.
Take the next digit (8) from the dividend and append it to 293, then repeat: 2938 / 347

Let's proceed to step 8:
2938 divided by 347 is 8 with a remainder of 162.
The next digit of our result is 8. 
Result so far: 192178.0
If we subtract 2776 from 2938, we 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.

Advancing to step 9:
If we divide 1620 by 347, we get 4 and a remainder of 232.
Use 4 as the next digit of our solution. 
Result so far: 192178.4
Deduct 1388 from 1620 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
When dividing 2320 by 347, we get 6 with a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 192178.46
Subtract 2082 from 2320 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 11:
When dividing 2380 by 347, we get 6 with a remainder of 298.
Put 6 as the next digit of the answer. 
Result so far: 192178.466
Deduct 2082 from 2380 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The quotient of the division is 192178.466, and the remainder is 0.0298.
