We look at the division of 337962 by 68 
The aim is to understand the frequency of 68 in 337962.

On to step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 68

On to step 2:
When dividing 33 by 68, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 68

Moving on to step 3:
337 divided by 68 is 4 with a remainder of 65.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 65 after subtracting 272 from 337.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 68

Moving on to step 4:
When dividing 659 by 68, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 612 from 659 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 68

Step 5:
476 divided by 68 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 497.0
The remainder is 0 after subtracting 476 from 476.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 68

On to step 6:
If we divide 2 by 68, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 4970.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 68 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4970.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 68 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 4970.02
Subtracting 136 from 200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
68 goes into 640 9 times with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 4970.029
If we subtract 612 from 640, we 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.

On to step 10:
68 can be fit into 280 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4970.0294
Subtracting 272 from 280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 68, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 4970.02941
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
If we divide 120 by 68, we get 1 and a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 4970.029411
If we take 68 away from 120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 4970.029411 with a remainder of 5.2e-06.
