Let's divide 66874218 by 122
The aim is to understand the frequency of 122 in 66874218.

On to step 1:
6 divided by 122 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 122

Going ahead to step 2:
If we divide 66 by 122, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 122

On to step 3:
If we divide 668 by 122, we get 5 and a remainder of 58.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 610 from 668 to get 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 122

Moving on to step 4:
When dividing 587 by 122, we get 4 with a remainder of 99.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 488 from 587 leaves us with 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 122

On to step 5:
When dividing 994 by 122, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 548.0
If we subtract 976 from 994, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 122

Let's proceed to step 6:
When dividing 182 by 122, we get 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 5481.0
Deduct 122 from 182 and we're left with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 122

Moving on to step 7:
The number 122 fits into 601 4 times, leaving a remainder of 113.
The next digit of our result is 4. 
Result so far: 54814.0
Deduct 488 from 601 and we're left with 113.
Include the next digit (8) from the dividend after 113, then repeat: 1138 / 122

Going ahead to step 8:
If we divide 1138 by 122, we get 9 and a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 548149.0
If we take 1098 away from 1138, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 122 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 548149.3
Subtracting 366 from 400 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 122 is 2 with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 548149.32
The remainder is 96 after subtracting 244 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
The number 122 fits into 960 7 times, leaving a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 548149.327
If we subtract 854 from 960, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 12:
The number 122 fits into 1060 8 times, leaving a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 548149.3278
If we take 976 away from 1060, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
122 goes into 840 6 times with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 548149.32786
Deduct 732 from 840 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
122 goes into 1080 8 times with a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 548149.327868
Deduct 976 from 1080 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 15:
122 can be fit into 1040 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 548149.3278688
Subtract 976 from 1040 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 548149.3278688 and a remainder of 6.4e-07.
