77543962 ÷ 248 
The aim is to understand the frequency of 248 in 77543962.

Advancing to step 1:
The number 248 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 248

On to step 2:
When dividing 77 by 248, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 248

Let's proceed to step 3:
The number 248 fits into 775 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 744 from 775, we get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 248

Advancing to step 4:
The number 248 fits into 314 1 times, leaving a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 248 away from 314, we end up with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 248

Advancing to step 5:
248 goes into 663 2 times with a remainder of 167.
Use 2 as the next digit of our solution. 
Result so far: 312.0
Subtract 496 from 663 to get 167.
Grab the next digit (9) from the dividend, add it to 167, then carry on: 1679 / 248

On to step 6:
248 goes into 1679 6 times with a remainder of 191.
Use 6 as the next digit of our solution. 
Result so far: 3126.0
The remainder is 191 after subtracting 1488 from 1679.
Include the next digit (6) from the dividend after 191, then repeat: 1916 / 248

Moving on to step 7:
1916 divided by 248 is 7 with a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 31267.0
Deduct 1736 from 1916 and we're left with 180.
Bring next digit (2) of the dividend behind the 180 and repeat the process: 1802 / 248

Let's proceed to step 8:
1802 divided by 248 is 7 with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 312677.0
Deduct 1736 from 1802 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
248 can be fit into 660 2 times, resulting in a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 312677.2
If we take 496 away from 660, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
When dividing 1640 by 248, we get 6 with a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 312677.26
Subtract 1488 from 1640 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
When dividing 1520 by 248, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 312677.266
If we subtract 1488 from 1520, 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.

Our division results in 312677.266 with a remaining 0.0032.
