We're dividing 412210 by 39 
The aim is to understand the frequency of 39 in 412210.

On to step 1:
If we divide 4 by 39, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 39

Moving on to step 2:
41 divided by 39 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 39 from 41 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 39

On to step 3:
If we divide 22 by 39, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 39

Let's proceed to step 4:
222 divided by 39 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtract 195 from 222 to get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 39

Let's proceed to step 5:
271 divided by 39 is 6 with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 1056.0
Subtract 234 from 271 to get 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 39

Advancing to step 6:
370 divided by 39 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 10569.0
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 7:
190 divided by 39 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 10569.4
Deduct 156 from 190 and we're left 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.

Going ahead to step 8:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10569.48
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:
280 divided by 39 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10569.487
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.

Moving on to step 10:
If we divide 70 by 39, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 10569.4871
Deduct 39 from 70 and we're left 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.

Moving on to step 11:
When dividing 310 by 39, we get 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 10569.48717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
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: 10569.487179
If we take 351 away from 370, we end up 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.

Let's proceed to step 13:
When dividing 190 by 39, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 10569.4871794
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
If we divide 340 by 39, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 10569.48717948
Deduct 312 from 340 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.

In conclusion, the division gives 10569.48717948 with a balance of 2.8e-08.
