We're dividing 456803 by 39 
The aim is to understand the frequency of 39 in 456803.

Going ahead to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 39

On to step 2:
39 can be fit into 45 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we take 39 away from 45, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 39

Advancing to step 3:
When dividing 66 by 39, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 39 from 66, we get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 39

Advancing to step 4:
The number 39 fits into 278 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 117.0
Deduct 273 from 278 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 39

Advancing to step 5:
39 can be fit into 50 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1171.0
If we take 39 away from 50, we end up with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 39

Step 6:
When dividing 113 by 39, we get 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 11712.0
Subtracting 78 from 113 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 39, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 11712.8
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 11712.89
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
39 goes into 290 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 11712.897
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
39 goes into 170 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 11712.8974
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 11712.89743
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
When dividing 230 by 39, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 11712.897435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
The number 39 fits into 350 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 11712.8974358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
380 divided by 39 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 11712.89743589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 11712.89743589 with a balance of 2.9e-08.
