We divide 147222 by 39
The aim is to understand the frequency of 39 in 147222.

Step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 39

Moving on to step 2:
If we divide 14 by 39, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 39

On to step 3:
If we divide 147 by 39, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 117 away from 147, we end up with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 39

On to step 4:
The number 39 fits into 302 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 273 from 302 leaves us with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 39

Step 5:
The number 39 fits into 292 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 377.0
If we take 273 away from 292, we end up with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 39

Moving on to step 6:
The number 39 fits into 192 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3774.0
If we subtract 156 from 192, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
39 goes into 360 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 3774.9
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
When dividing 90 by 39, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3774.92
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 39 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3774.923
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
If we divide 30 by 39, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3774.923
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 39, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 3774.92307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
The number 39 fits into 270 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 3774.923076
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 3774.9230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
If we divide 90 by 39, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3774.92307692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 3774.92307692, with a leftover of 1.2e-08.
