80738738 divided by 68 
The aim is to understand the frequency of 68 in 80738738.

On to step 1:
When dividing 8 by 68, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 68

On to step 2:
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: 1.0
If we subtract 68 from 80, we get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 68

Going ahead to step 3:
The number 68 fits into 127 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 68 from 127, we get 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 68

Moving on to step 4:
593 divided by 68 is 8 with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtract 544 from 593 to get 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 68

Moving on to step 5:
68 goes into 498 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 1187.0
The remainder is 22 after subtracting 476 from 498.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 68

Step 6:
227 divided by 68 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 11873.0
Deduct 204 from 227 and we're left with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 68

Moving on to step 7:
If we divide 233 by 68, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 118733.0
If we subtract 204 from 233, we get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 68

Advancing to step 8:
298 divided by 68 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1187334.0
If we take 272 away from 298, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
68 can be fit into 260 3 times, resulting in a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 1187334.3
Subtracting 204 from 260 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
The number 68 fits into 560 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1187334.38
Subtract 544 from 560 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 68 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1187334.382
The remainder is 24 after subtracting 136 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 68, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 1187334.3823
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
68 can be fit into 360 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 1187334.38235
Subtract 340 from 360 to 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.

Going ahead to step 14:
The number 68 fits into 200 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 1187334.382352
If we take 136 away from 200, we end up 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.

Let's proceed to step 15:
If we divide 640 by 68, we get 9 and a remainder of 28.
The next digit of our result is 9. 
Result so far: 1187334.3823529
The remainder is 28 after subtracting 612 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
If we divide 280 by 68, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1187334.38235294
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.

The final outcome is 1187334.38235294, with a leftover of 8e-09.
