We look at the division of 59702472 by 215 
The aim is to understand the frequency of 215 in 59702472.

On to step 1:
If we divide 5 by 215, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 215

Going ahead to step 2:
The number 215 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 215

Moving on to step 3:
597 divided by 215 is 2 with a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 430 from 597 leaves us with 167.
Grab the next digit (0) from the dividend, add it to 167, then carry on: 1670 / 215

Moving on to step 4:
If we divide 1670 by 215, we get 7 and a remainder of 165.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 1505 from 1670 to get 165.
Include the next digit (2) from the dividend after 165, then repeat: 1652 / 215

Advancing to step 5:
The number 215 fits into 1652 7 times, leaving a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 277.0
The remainder is 147 after subtracting 1505 from 1652.
Include the next digit (4) from the dividend after 147, then repeat: 1474 / 215

Advancing to step 6:
If we divide 1474 by 215, we get 6 and a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 2776.0
Deduct 1290 from 1474 and we're left with 184.
Include the next digit (7) from the dividend after 184, then repeat: 1847 / 215

Let's proceed to step 7:
When dividing 1847 by 215, we get 8 with a remainder of 127.
Write down 8 as next digit of the result. 
Result so far: 27768.0
If we take 1720 away from 1847, we end up with 127.
Fetch the next digit (2) from the dividend, attach it to 127 and continue: 1272 / 215

Advancing to step 8:
1272 divided by 215 is 5 with a remainder of 197.
Write down 5 as next digit of the result. 
Result so far: 277685.0
Deduct 1075 from 1272 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 9:
215 goes into 1970 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 277685.9
Subtract 1935 from 1970 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
215 can be fit into 350 1 times, resulting in a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 277685.91
The remainder is 135 after subtracting 215 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
215 goes into 1350 6 times with a remainder of 60.
The next digit of our result is 6. 
Result so far: 277685.916
If we subtract 1290 from 1350, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
215 can be fit into 600 2 times, resulting in a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 277685.9162
Subtract 430 from 600 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 13:
215 can be fit into 1700 7 times, resulting in a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 277685.91627
The remainder is 195 after subtracting 1505 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 14:
1950 divided by 215 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 277685.916279
Subtracting 1935 from 1950 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.

Going ahead to step 15:
215 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 277685.916279
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
215 goes into 1500 6 times with a remainder of 210.
Record the quotient 6 as the next digit in the result. 
Result so far: 277685.91627906
The remainder is 210 after subtracting 1290 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 277685.91627906, with a leftover of 2.1e-07.
