We're dividing 23803 by 61 
The aim is to understand the frequency of 61 in 23803.

On to step 1:
2 divided by 61 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 61

On to step 2:
61 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 61

Let's proceed to step 3:
The number 61 fits into 238 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 183 from 238, we get 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 61

On to step 4:
The number 61 fits into 550 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 549 from 550, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 61

Moving on to step 5:
When dividing 13 by 61, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
The number 61 fits into 130 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 390.2
Deduct 122 from 130 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 61, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 390.21
Subtracting 61 from 80 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
61 goes into 190 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 390.213
The remainder is 7 after subtracting 183 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
When dividing 70 by 61, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 390.2131
Subtract 61 from 70 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
61 can be fit into 90 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 390.21311
If we subtract 61 from 90, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 390.21311, and the remainder is 2.9e-05.
