We look at the division of 121706 by 74 
The aim is to understand the frequency of 74 in 121706.

On to step 1:
1 divided by 74 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 74

Going ahead to step 2:
The number 74 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 74

Moving on to step 3:
121 divided by 74 is 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 74 from 121, we get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 74

Going ahead to step 4:
74 goes into 477 6 times with a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 444 from 477 and we're left with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 74

Moving on to step 5:
When dividing 330 by 74, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we take 296 away from 330, we end up with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 74

Moving on to step 6:
74 goes into 346 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 1644.0
Deduct 296 from 346 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
500 divided by 74 is 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 1644.6
Subtract 444 from 500 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
When dividing 560 by 74, we get 7 with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 1644.67
The remainder is 42 after subtracting 518 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
420 divided by 74 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1644.675
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
74 can be fit into 500 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 1644.6756
Subtract 444 from 500 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
When dividing 560 by 74, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 1644.67567
If we take 518 away from 560, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
If we divide 420 by 74, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1644.675675
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
If we divide 500 by 74, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 1644.6756756
Subtracting 444 from 500 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 14:
When dividing 560 by 74, we get 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 1644.67567567
Subtract 518 from 560 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 1644.67567567 with a remainder of 4.2e-08.
