77112603 divided by 548 
The aim is to understand the frequency of 548 in 77112603.

On to step 1:
If we divide 7 by 548, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 548

Going ahead to step 2:
548 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 548

Let's proceed to step 3:
771 divided by 548 is 1 with a remainder of 223.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 548 from 771 leaves us with 223.
Take the next digit (1) from the dividend and append it to 223, then repeat: 2231 / 548

Let's proceed to step 4:
When dividing 2231 by 548, we get 4 with a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2192 from 2231 to get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 548

Let's proceed to step 5:
The number 548 fits into 392 0 times, leaving a remainder of 392.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Deduct 0 from 392 and we're left with 392.
Grab the next digit (6) from the dividend, add it to 392, then carry on: 3926 / 548

Let's proceed to step 6:
The number 548 fits into 3926 7 times, leaving a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 1407.0
Subtract 3836 from 3926 to get 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 548

On to step 7:
The number 548 fits into 900 1 times, leaving a remainder of 352.
Record the quotient 1 as the next digit in the result. 
Result so far: 14071.0
Deduct 548 from 900 and we're left with 352.
Grab the next digit (3) from the dividend, add it to 352, then carry on: 3523 / 548

Moving on to step 8:
548 can be fit into 3523 6 times, resulting in a remainder of 235.
The number 6 becomes the next digit in our result. 
Result so far: 140716.0
Subtract 3288 from 3523 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 9:
If we divide 2350 by 548, we get 4 and a remainder of 158.
The next digit of our result is 4. 
Result so far: 140716.4
If we subtract 2192 from 2350, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
548 can be fit into 1580 2 times, resulting in a remainder of 484.
Write down 2 as next digit of the result. 
Result so far: 140716.42
The remainder is 484 after subtracting 1096 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 11:
If we divide 4840 by 548, we get 8 and a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 140716.428
Deduct 4384 from 4840 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 12:
548 goes into 4560 8 times with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 140716.4288
If we subtract 4384 from 4560, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Our division results in 140716.4288 with a remaining 0.00176.
