We look at the division of 747133 by 74 
The aim is to understand the frequency of 74 in 747133.

Advancing to step 1:
If we divide 7 by 74, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 74

Let's proceed to step 2:
When dividing 74 by 74, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 74 from 74, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 74

Step 3:
When dividing 7 by 74, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 74

Going ahead to step 4:
If we divide 71 by 74, we get 0 and a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 74

Advancing to step 5:
713 divided by 74 is 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 1009.0
The remainder is 47 after subtracting 666 from 713.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 74

On to step 6:
74 can be fit into 473 6 times, resulting in a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 10096.0
The remainder is 29 after subtracting 444 from 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 74, we get 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 10096.3
The remainder is 68 after subtracting 222 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
The number 74 fits into 680 9 times, leaving a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 10096.39
Subtracting 666 from 680 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 74 fits into 140 1 times, leaving a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 10096.391
The remainder is 66 after subtracting 74 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
660 divided by 74 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 10096.3918
The remainder is 68 after subtracting 592 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
When dividing 680 by 74, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 10096.39189
Deduct 666 from 680 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 74, we get 1 with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 10096.391891
If we subtract 74 from 140, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
When dividing 660 by 74, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 10096.3918918
Deduct 592 from 660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
The number 74 fits into 680 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 10096.39189189
The remainder is 14 after subtracting 666 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 10096.39189189 and a remainder of 1.4e-08.
