944845 divided by 39 
The aim is to understand the frequency of 39 in 944845.

On to step 1:
9 divided by 39 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 39

Advancing to step 2:
When dividing 94 by 39, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 78 from 94 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 39

Moving on to step 3:
The number 39 fits into 164 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 8 after subtracting 156 from 164.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 39

Step 4:
When dividing 88 by 39, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 242.0
Subtract 78 from 88 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 39

Going ahead to step 5:
If we divide 104 by 39, we get 2 and a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2422.0
Subtracting 78 from 104 leaves us with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 39

Going ahead to step 6:
265 divided by 39 is 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 24226.0
If we subtract 234 from 265, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
If we divide 310 by 39, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 24226.7
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.

Going ahead to step 8:
If we divide 370 by 39, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 24226.79
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 39 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 24226.794
If we subtract 156 from 190, we get 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 10:
39 goes into 340 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 24226.7948
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.

On to step 11:
If we divide 280 by 39, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 24226.79487
If we subtract 273 from 280, we get 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 12:
70 divided by 39 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 24226.794871
If we take 39 away from 70, we end up 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.

Let's proceed to step 13:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 24226.7948717
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.

Step 14:
39 goes into 370 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 24226.79487179
Deduct 351 from 370 and we're left 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.

The quotient of the division is 24226.79487179, and the remainder is 1.9e-08.
