85624905 ÷ 39 
The aim is to understand the frequency of 39 in 85624905.

On to step 1:
When dividing 8 by 39, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 39

Going ahead to step 2:
If we divide 85 by 39, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 7 after subtracting 78 from 85.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 39

Step 3:
If we divide 76 by 39, we get 1 and a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 39 from 76, we get 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 39

Going ahead to step 4:
The number 39 fits into 372 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
If we subtract 351 from 372, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 39

Going ahead to step 5:
When dividing 214 by 39, we get 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 2195.0
Subtract 195 from 214 to get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 39

Advancing to step 6:
If we divide 199 by 39, we get 5 and a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 21955.0
Deduct 195 from 199 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 39

Moving on to step 7:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 219551.0
If we subtract 39 from 40, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 39

Moving on to step 8:
The number 39 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 2195510.0
Subtracting 0 from 15 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 39 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 2195510.3
Subtract 117 from 150 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
When dividing 330 by 39, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 2195510.38
Deduct 312 from 330 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2195510.384
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 39, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2195510.3846
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
39 goes into 60 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 2195510.38461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
If we divide 210 by 39, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2195510.384615
If we take 195 away from 210, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 15:
When dividing 150 by 39, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 2195510.3846153
Subtracting 117 from 150 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 16:
When dividing 330 by 39, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 2195510.38461538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 2195510.38461538, and the remainder is 1.8e-08.
