We're dividing 78556648 by 61 
The aim is to understand the frequency of 61 in 78556648.

Let's proceed to step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 61

Advancing to step 2:
If we divide 78 by 61, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 61 from 78 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 61

Moving on to step 3:
61 goes into 175 2 times with a remainder of 53.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 122 from 175 and we're left with 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 61

On to step 4:
The number 61 fits into 535 8 times, leaving a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 128.0
Subtracting 488 from 535 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 61

Advancing to step 5:
61 can be fit into 476 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
Deduct 427 from 476 and we're left with 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 61

Moving on to step 6:
61 can be fit into 496 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 12878.0
Subtract 488 from 496 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 61

Going ahead to step 7:
61 can be fit into 84 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 128781.0
The remainder is 23 after subtracting 61 from 84.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 61

Let's proceed to step 8:
The number 61 fits into 238 3 times, leaving a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 1287813.0
If we take 183 away from 238, we end up 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 9:
When dividing 550 by 61, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1287813.9
The remainder is 1 after subtracting 549 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 61 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1287813.9
If we subtract 0 from 10, we 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 11:
100 divided by 61 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1287813.901
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 12:
390 divided by 61 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1287813.9016
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.

Step 13:
240 divided by 61 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 1287813.90163
If we take 183 away from 240, we end up with 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 14:
61 goes into 570 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 1287813.901639
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 15:
When dividing 210 by 61, we get 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 1287813.9016393
Subtracting 183 from 210 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 16:
When dividing 270 by 61, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 1287813.90163934
Subtracting 244 from 270 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 1287813.90163934, and the remainder is 2.6e-08.
