85609642 ÷ 39 
The aim is to understand the frequency of 39 in 85609642.

Let's proceed to step 1:
8 divided by 39 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 39

Going ahead to step 2:
When dividing 85 by 39, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 78 from 85 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 39

Step 3:
39 can be fit into 76 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 37 after subtracting 39 from 76.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 39

Moving on to step 4:
When dividing 370 by 39, we get 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
If we take 351 away from 370, we end up with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 39

Moving on to step 5:
199 divided by 39 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 2195.0
Subtracting 195 from 199 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 39

Step 6:
39 can be fit into 46 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 21951.0
Deduct 39 from 46 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 39

Let's proceed to step 7:
39 can be fit into 74 1 times, resulting in a remainder of 35.
The next digit of our result is 1. 
Result so far: 219511.0
Deduct 39 from 74 and we're left with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 39

On to step 8:
If we divide 352 by 39, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2195119.0
The remainder is 1 after subtracting 351 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
10 divided by 39 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2195119.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
39 can be fit into 100 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2195119.02
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
If we divide 220 by 39, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2195119.025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2195119.0256
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 39, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 2195119.02564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
The number 39 fits into 40 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2195119.025641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 15:
If we divide 10 by 39, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2195119.025641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2195119.02564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 2195119.02564102, and the remainder is 2.2e-08.
