We're dividing 900346 by 39 
The aim is to understand the frequency of 39 in 900346.

Let's proceed to step 1:
39 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 39

Moving on to step 2:
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: 2.0
The remainder is 12 after subtracting 78 from 90.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 39

Advancing to step 3:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 117 from 120 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 39

On to step 4:
39 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Subtract 0 from 33 to get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 39

Step 5:
When dividing 334 by 39, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 2308.0
The remainder is 22 after subtracting 312 from 334.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 39

Moving on to step 6:
39 can be fit into 226 5 times, resulting in a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 23085.0
If we subtract 195 from 226, 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.

Let's proceed to step 7:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 23085.7
If we subtract 273 from 310, we 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.

Going ahead to step 8:
39 goes into 370 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 23085.79
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.

On to step 9:
39 goes into 190 4 times with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 23085.794
Subtracting 156 from 190 leaves us 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 10:
If we divide 340 by 39, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 23085.7948
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.

Going ahead to step 11:
39 goes into 280 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 23085.79487
Subtracting 273 from 280 leaves us 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.

Going ahead to step 12:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 23085.794871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
The number 39 fits into 310 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 23085.7948717
Deduct 273 from 310 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.

Going ahead to step 14:
If we divide 370 by 39, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 23085.79487179
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.

Our division results in 23085.79487179 with a remaining 1.9e-08.
