Let's divide 56431 by 39
The aim is to understand the frequency of 39 in 56431.

Moving on to step 1:
5 divided by 39 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 39

Moving on to step 2:
39 goes into 56 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 56 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 39

On to step 3:
The number 39 fits into 174 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 156 from 174, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 39

Advancing to step 4:
39 can be fit into 183 4 times, resulting in a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we subtract 156 from 183, we get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 39

Advancing to step 5:
When dividing 271 by 39, we get 6 with a remainder of 37.
The next digit of our result is 6. 
Result so far: 1446.0
Deduct 234 from 271 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 6:
When dividing 370 by 39, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 1446.9
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1446.94
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
39 goes into 340 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1446.948
Subtracting 312 from 340 leaves us 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.

On to step 9:
When dividing 280 by 39, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1446.9487
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
When dividing 70 by 39, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1446.94871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
When dividing 310 by 39, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 1446.948717
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
When dividing 370 by 39, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 1446.9487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
190 divided by 39 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 1446.94871794
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 1446.94871794 with a balance of 3.4e-08.
