We're dividing 456290 by 61 
The aim is to understand the frequency of 61 in 456290.

Step 1:
The number 61 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 61

Let's proceed to step 2:
45 divided by 61 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 61

Step 3:
When dividing 456 by 61, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 427 from 456 leaves us with 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 61

Let's proceed to step 4:
When dividing 292 by 61, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 244 from 292 and we're left with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 61

Moving on to step 5:
61 can be fit into 489 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 748.0
Deduct 488 from 489 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 61

Step 6:
61 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7480.0
Subtract 0 from 10 to 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.

Going ahead to step 7:
61 can be fit into 100 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 7480.1
Subtracting 61 from 100 leaves us 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.

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: 7480.16
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.

Going ahead to step 9:
61 can be fit into 240 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 7480.163
Subtract 183 from 240 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 10:
570 divided by 61 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 7480.1639
If we subtract 549 from 570, we 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.

Advancing to step 11:
If we divide 210 by 61, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 7480.16393
Subtract 183 from 210 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
61 can be fit into 270 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 7480.163934
The remainder is 26 after subtracting 244 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
The number 61 fits into 260 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7480.1639344
Subtract 244 from 260 to get 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 quotient of the division is 7480.1639344, and the remainder is 1.6e-07.
