Let's divide 59165849 by 15
The aim is to understand the frequency of 15 in 59165849.

Advancing to step 1:
15 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 15

Going ahead to step 2:
15 can be fit into 59 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 45 from 59 leaves us with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 15

Going ahead to step 3:
15 can be fit into 141 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 135 from 141 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 15

On to step 4:
15 can be fit into 66 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 394.0
The remainder is 6 after subtracting 60 from 66.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

On to step 5:
If we divide 65 by 15, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 3944.0
If we subtract 60 from 65, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 15

Advancing to step 6:
When dividing 58 by 15, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 39443.0
If we take 45 away from 58, we end up with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 15

Advancing to step 7:
If we divide 134 by 15, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 394438.0
If we take 120 away from 134, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 15

Going ahead to step 8:
If we divide 149 by 15, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 3944389.0
If we subtract 135 from 149, we 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.

Going ahead to step 9:
15 goes into 140 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 3944389.9
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3944389.93
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3944389.933
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 3944389.933, with a leftover of 0.0005.
