61826948 ÷ 61 
The aim is to understand the frequency of 61 in 61826948.

Advancing to step 1:
When dividing 6 by 61, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 61

On to step 2:
If we divide 61 by 61, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 61 from 61.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 61

Step 3:
61 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 61

Going ahead to step 4:
82 divided by 61 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 101.0
The remainder is 21 after subtracting 61 from 82.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 61

Going ahead to step 5:
The number 61 fits into 216 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
Deduct 183 from 216 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 61

Let's proceed to step 6:
339 divided by 61 is 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 10135.0
If we take 305 away from 339, we end up with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 61

Step 7:
344 divided by 61 is 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 101355.0
If we take 305 away from 344, we end up with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 61

On to step 8:
398 divided by 61 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1013556.0
If we subtract 366 from 398, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 61, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1013556.5
Subtracting 305 from 320 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 61 fits into 150 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1013556.52
The remainder is 28 after subtracting 122 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
61 can be fit into 280 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1013556.524
If we subtract 244 from 280, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 61 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1013556.5245
Subtracting 305 from 360 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
550 divided by 61 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1013556.52459
If we take 549 away from 550, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
When dividing 10 by 61, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1013556.52459
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 61 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1013556.5245901
Subtract 61 from 100 to get 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 16:
When dividing 390 by 61, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1013556.52459016
Subtract 366 from 390 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1013556.52459016 and a remainder of 2.4e-08.
