90779103 ÷ 39 
The aim is to understand the frequency of 39 in 90779103.

Going ahead to step 1:
The number 39 fits into 9 0 times, leaving 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.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 39

Going ahead to step 2:
39 goes into 90 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 78 from 90 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 39

Let's proceed to step 3:
If we divide 127 by 39, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 117 from 127 and we're left with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 39

Advancing to step 4:
39 goes into 107 2 times with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
Subtracting 78 from 107 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 39

Advancing to step 5:
When dividing 299 by 39, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 2327.0
Subtract 273 from 299 to get 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 39

Moving on to step 6:
If we divide 261 by 39, we get 6 and a remainder of 27.
The next digit of our result is 6. 
Result so far: 23276.0
Deduct 234 from 261 and we're left with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 39

Advancing to step 7:
270 divided by 39 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 232766.0
Deduct 234 from 270 and we're left with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 39

On to step 8:
The number 39 fits into 363 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 2327669.0
Subtracting 351 from 363 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 39 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2327669.3
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2327669.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 39 fits into 300 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 2327669.307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
When dividing 270 by 39, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 2327669.3076
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 2327669.30769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
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: 2327669.307692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2327669.3076923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 16:
When dividing 30 by 39, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2327669.3076923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 2327669.3076923, and the remainder is 3e-08.
