217719 ÷ 61 
The aim is to understand the frequency of 61 in 217719.

On to step 1:
61 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 61

Moving on to step 2:
When dividing 21 by 61, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 61

On to step 3:
When dividing 217 by 61, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 183 from 217 to get 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 61

Moving on to step 4:
61 can be fit into 347 5 times, resulting in a remainder of 42.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 305 from 347 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 61

Step 5:
61 goes into 421 6 times with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
Subtracting 366 from 421 leaves us with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 61

Going ahead to step 6:
559 divided by 61 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3569.0
If we subtract 549 from 559, we 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.

Advancing to step 7:
61 goes into 100 1 times with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 3569.1
If we take 61 away from 100, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
390 divided by 61 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 3569.16
Deduct 366 from 390 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 61 is 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 3569.163
If we take 183 away from 240, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
When dividing 570 by 61, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 3569.1639
Subtract 549 from 570 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.

Let's proceed to step 11:
If we divide 210 by 61, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 3569.16393
Subtracting 183 from 210 leaves us 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.

Moving on to step 12:
61 can be fit into 270 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3569.163934
Subtract 244 from 270 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 61 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 3569.1639344
If we take 244 away from 260, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 3569.1639344 with a remainder of 1.6e-07.
