54987888 ÷ 79 
The aim is to understand the frequency of 79 in 54987888.

Let's proceed to step 1:
When dividing 5 by 79, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 79

Going ahead to step 2:
79 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 79

Going ahead to step 3:
When dividing 549 by 79, we get 6 with a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 474 from 549 and we're left with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 79

Step 4:
When dividing 758 by 79, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we take 711 away from 758, we end up with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 79

Step 5:
If we divide 477 by 79, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 696.0
Deduct 474 from 477 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 79

Let's proceed to step 6:
38 divided by 79 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 6960.0
If we take 0 away from 38, we end up with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 79

Advancing to step 7:
If we divide 388 by 79, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 69604.0
Subtract 316 from 388 to get 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 79

Step 8:
When dividing 728 by 79, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 696049.0
Subtract 711 from 728 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
79 goes into 170 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 696049.2
Subtract 158 from 170 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
79 goes into 120 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 696049.21
Deduct 79 from 120 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
410 divided by 79 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 696049.215
The remainder is 15 after subtracting 395 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
The number 79 fits into 150 1 times, leaving a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 696049.2151
Subtract 79 from 150 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
710 divided by 79 is 8 with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 696049.21518
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 14:
79 goes into 780 9 times with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 696049.215189
Deduct 711 from 780 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 15:
79 can be fit into 690 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 696049.2151898
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 16:
When dividing 580 by 79, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 696049.21518987
Subtracting 553 from 580 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.

The final result is 696049.21518987 with a remainder of 2.7e-08.
