Let's divide 66370 by 68
The aim is to understand the frequency of 68 in 66370.

Step 1:
The number 68 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 68

Going ahead to step 2:
If we divide 66 by 68, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 68

Going ahead to step 3:
When dividing 663 by 68, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 612 from 663 to get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 68

Moving on to step 4:
The number 68 fits into 517 7 times, leaving a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtracting 476 from 517 leaves us with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 68

On to step 5:
When dividing 410 by 68, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 976.0
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
When dividing 20 by 68, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 976.0
The remainder is 20 after subtracting 0 from 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 7:
68 goes into 200 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 976.02
Subtract 136 from 200 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
640 divided by 68 is 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 976.029
If we take 612 away from 640, we end up 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.

Advancing to step 9:
If we divide 280 by 68, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 976.0294
The remainder is 8 after subtracting 272 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 976.02941
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 68 fits into 120 1 times, leaving a remainder of 52.
The next digit of our result is 1. 
Result so far: 976.029411
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 outcome is 976.029411, with a leftover of 5.2e-06.
