438554 ÷ 61 
The aim is to understand the frequency of 61 in 438554.

Step 1:
4 divided by 61 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 61

Let's proceed to step 2:
43 divided by 61 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 61

Going ahead to step 3:
If we divide 438 by 61, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 427 from 438 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 61

Moving on to step 4:
The number 61 fits into 115 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 61 from 115, we get 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 61

Let's proceed to step 5:
When dividing 545 by 61, we get 8 with a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
Subtract 488 from 545 to get 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 61

On to step 6:
574 divided by 61 is 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 7189.0
Deduct 549 from 574 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
250 divided by 61 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 7189.4
Subtract 244 from 250 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 61 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7189.4
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 61, we get 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 7189.409
If we take 549 away from 600, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
61 goes into 510 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 7189.4098
If we subtract 488 from 510, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
61 can be fit into 220 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 7189.40983
Subtract 183 from 220 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
When dividing 370 by 61, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7189.409836
The remainder is 4 after subtracting 366 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 61 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7189.409836
Subtract 0 from 40 to get 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 14:
400 divided by 61 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 7189.40983606
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.

Our division results in 7189.40983606 with a remaining 3.4e-08.
