142308 divided by 74 
The aim is to understand the frequency of 74 in 142308.

On to step 1:
If we divide 1 by 74, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 74

Step 2:
The number 74 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 74

Step 3:
The number 74 fits into 142 1 times, leaving a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 74 from 142 leaves us with 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 74

On to step 4:
683 divided by 74 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 19.0
If we take 666 away from 683, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 74

Going ahead to step 5:
The number 74 fits into 170 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
If we take 148 away from 170, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 74

On to step 6:
74 can be fit into 228 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1923.0
If we take 222 away from 228, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 74 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1923.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 74, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1923.08
Deduct 592 from 600 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 74, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1923.081
If we take 74 away from 80, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
When dividing 60 by 74, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 1923.081
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 74 fits into 600 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 1923.08108
Subtracting 592 from 600 leaves us with 8.
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 12:
74 can be fit into 80 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1923.081081
Subtract 74 from 80 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 74 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 1923.081081
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
The number 74 fits into 600 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 1923.08108108
If we take 592 away from 600, we end up with 8.
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 1923.08108108, with a leftover of 8e-09.
