67221121 ÷ 177 
The aim is to understand the frequency of 177 in 67221121.

Step 1:
The number 177 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 177

Step 2:
When dividing 67 by 177, we get 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 177

On to step 3:
177 can be fit into 672 3 times, resulting in a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 531 from 672 and we're left with 141.
Fetch the next digit (2) from the dividend, attach it to 141 and continue: 1412 / 177

Going ahead to step 4:
The number 177 fits into 1412 7 times, leaving a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 1239 from 1412 to get 173.
Include the next digit (1) from the dividend after 173, then repeat: 1731 / 177

Let's proceed to step 5:
1731 divided by 177 is 9 with a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 379.0
The remainder is 138 after subtracting 1593 from 1731.
Fetch the next digit (1) from the dividend, attach it to 138 and continue: 1381 / 177

Step 6:
If we divide 1381 by 177, we get 7 and a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 3797.0
If we take 1239 away from 1381, we end up with 142.
Grab the next digit (2) from the dividend, add it to 142, then carry on: 1422 / 177

Let's proceed to step 7:
The number 177 fits into 1422 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 37978.0
Subtracting 1416 from 1422 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 177

On to step 8:
If we divide 61 by 177, we get 0 and a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 379780.0
Subtracting 0 from 61 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
The number 177 fits into 610 3 times, leaving a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 379780.3
The remainder is 79 after subtracting 531 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
The number 177 fits into 790 4 times, leaving a remainder of 82.
The next digit of our result is 4. 
Result so far: 379780.34
The remainder is 82 after subtracting 708 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
177 goes into 820 4 times with a remainder of 112.
The next digit of our result is 4. 
Result so far: 379780.344
Subtracting 708 from 820 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 379780.344 and a remainder of 0.0112.
