We look at the division of 867123 by 74 
The aim is to understand the frequency of 74 in 867123.

On to step 1:
8 divided by 74 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 74

Advancing to step 2:
If we divide 86 by 74, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 74 from 86 and we're left with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 74

Moving on to step 3:
When dividing 127 by 74, we get 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 74 from 127 and we're left with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 74

Going ahead to step 4:
74 goes into 531 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtracting 518 from 531 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 74

On to step 5:
132 divided by 74 is 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1171.0
Deduct 74 from 132 and we're left with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 74

Advancing to step 6:
When dividing 583 by 74, we get 7 with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 11717.0
Deduct 518 from 583 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
74 can be fit into 650 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 11717.8
Subtract 592 from 650 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
If we divide 580 by 74, we get 7 and a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 11717.87
Subtract 518 from 580 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
620 divided by 74 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 11717.878
Deduct 592 from 620 and we're left 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 10:
If we divide 280 by 74, we get 3 and a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 11717.8783
If we take 222 away from 280, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
The number 74 fits into 580 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 11717.87837
If we subtract 518 from 580, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
The number 74 fits into 620 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 11717.878378
The remainder is 28 after subtracting 592 from 620.
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 13:
The number 74 fits into 280 3 times, leaving a remainder of 58.
The next digit of our result is 3. 
Result so far: 11717.8783783
If we take 222 away from 280, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
When dividing 580 by 74, we get 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 11717.87837837
Subtracting 518 from 580 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 11717.87837837 and a remainder of 6.2e-08.
