20937863 ÷ 61 
The aim is to understand the frequency of 61 in 20937863.

Step 1:
61 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 61

Moving on to step 2:
61 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 61

Going ahead to step 3:
When dividing 209 by 61, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 183 from 209 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 61

Step 4:
263 divided by 61 is 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 244 from 263, we get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 61

Let's proceed to step 5:
If we divide 197 by 61, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 343.0
Subtract 183 from 197 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 61

Moving on to step 6:
When dividing 148 by 61, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 3432.0
The remainder is 26 after subtracting 122 from 148.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 61

Let's proceed to step 7:
61 goes into 266 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 34324.0
If we subtract 244 from 266, we get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 61

Advancing to step 8:
223 divided by 61 is 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 343243.0
If we take 183 away from 223, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 61, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 343243.6
Subtract 366 from 400 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
340 divided by 61 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 343243.65
If we subtract 305 from 340, we 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.

Step 11:
350 divided by 61 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 343243.655
The remainder is 45 after subtracting 305 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 343243.655 with a balance of 0.0045.
