458099 ÷ 61 
The aim is to understand the frequency of 61 in 458099.

Step 1:
If we divide 4 by 61, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 61

On to step 2:
61 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 61

On to step 3:
61 goes into 458 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 427 from 458, we get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 61

Moving on to step 4:
When dividing 310 by 61, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 305 from 310 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 61

Let's proceed to step 5:
When dividing 59 by 61, we get 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 750.0
Subtracting 0 from 59 leaves us with 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 61

Step 6:
599 divided by 61 is 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 7509.0
Deduct 549 from 599 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
When dividing 500 by 61, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 7509.8
Subtracting 488 from 500 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
61 goes into 120 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 7509.81
Deduct 61 from 120 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
When dividing 590 by 61, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 7509.819
The remainder is 41 after subtracting 549 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
If we divide 410 by 61, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 7509.8196
If we subtract 366 from 410, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
The number 61 fits into 440 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 7509.81967
Subtracting 427 from 440 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
61 goes into 130 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7509.819672
If we subtract 122 from 130, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
80 divided by 61 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 7509.8196721
If we take 61 away from 80, we end up 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.

Advancing to step 14:
When dividing 190 by 61, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 7509.81967213
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.

After the division, we end up with 7509.81967213 and a remainder of 7e-09.
