68554918 divided by 948 
The aim is to understand the frequency of 948 in 68554918.

Let's proceed to step 1:
6 divided by 948 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 948

Going ahead to step 2:
948 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 948

On to step 3:
If we divide 685 by 948, we get 0 and a remainder of 685.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 685 leaves us with 685.
Bring next digit (5) of the dividend behind the 685 and repeat the process: 6855 / 948

Going ahead to step 4:
When dividing 6855 by 948, we get 7 with a remainder of 219.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 6636 from 6855, we get 219.
Bring next digit (4) of the dividend behind the 219 and repeat the process: 2194 / 948

Moving on to step 5:
The number 948 fits into 2194 2 times, leaving a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 1896 from 2194 leaves us with 298.
Grab the next digit (9) from the dividend, add it to 298, then carry on: 2989 / 948

Moving on to step 6:
When dividing 2989 by 948, we get 3 with a remainder of 145.
The next digit of our result is 3. 
Result so far: 723.0
Subtract 2844 from 2989 to get 145.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 948

Advancing to step 7:
The number 948 fits into 1451 1 times, leaving a remainder of 503.
Use 1 as the next digit of our solution. 
Result so far: 7231.0
The remainder is 503 after subtracting 948 from 1451.
Include the next digit (8) from the dividend after 503, then repeat: 5038 / 948

Going ahead to step 8:
5038 divided by 948 is 5 with a remainder of 298.
Use 5 as the next digit of our solution. 
Result so far: 72315.0
Deduct 4740 from 5038 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
2980 divided by 948 is 3 with a remainder of 136.
The next digit of our result is 3. 
Result so far: 72315.3
The remainder is 136 after subtracting 2844 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
948 can be fit into 1360 1 times, resulting in a remainder of 412.
Use 1 as the next digit of our solution. 
Result so far: 72315.31
Subtract 948 from 1360 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 11:
948 goes into 4120 4 times with a remainder of 328.
The next digit of our result is 4. 
Result so far: 72315.314
Subtract 3792 from 4120 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
When dividing 3280 by 948, we get 3 with a remainder of 436.
Write down 3 as next digit of the result. 
Result so far: 72315.3143
Subtract 2844 from 3280 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 13:
948 goes into 4360 4 times with a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 72315.31434
Deduct 3792 from 4360 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 14:
948 can be fit into 5680 5 times, resulting in a remainder of 940.
Use 5 as the next digit of our solution. 
Result so far: 72315.314345
Subtracting 4740 from 5680 leaves us with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

On to step 15:
When dividing 9400 by 948, we get 9 with a remainder of 868.
Use 9 as the next digit of our solution. 
Result so far: 72315.3143459
Subtract 8532 from 9400 to get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Step 16:
If we divide 8680 by 948, we get 9 and a remainder of 148.
Write down 9 as next digit of the result. 
Result so far: 72315.31434599
Subtract 8532 from 8680 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 72315.31434599 and a remainder of 1.48e-07.
