66967208 ÷ 988 
The aim is to understand the frequency of 988 in 66967208.

Advancing to step 1:
When dividing 6 by 988, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 988

On to step 2:
988 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 988

Going ahead to step 3:
The number 988 fits into 669 0 times, leaving a remainder of 669.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 669 after subtracting 0 from 669.
Append the next digit (6) from the dividend to 669 and continue with: 6696 / 988

Moving on to step 4:
The number 988 fits into 6696 6 times, leaving a remainder of 768.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5928 away from 6696, we end up with 768.
Grab the next digit (7) from the dividend, add it to 768, then carry on: 7687 / 988

Advancing to step 5:
If we divide 7687 by 988, we get 7 and a remainder of 771.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 6916 from 7687, we get 771.
Include the next digit (2) from the dividend after 771, then repeat: 7712 / 988

Moving on to step 6:
The number 988 fits into 7712 7 times, leaving a remainder of 796.
Use 7 as the next digit of our solution. 
Result so far: 677.0
The remainder is 796 after subtracting 6916 from 7712.
Append the next digit (0) from the dividend to 796 and continue with: 7960 / 988

Advancing to step 7:
If we divide 7960 by 988, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 6778.0
Subtracting 7904 from 7960 leaves us with 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 988

Let's proceed to step 8:
988 can be fit into 568 0 times, resulting in a remainder of 568.
Put 0 as the next digit of the answer. 
Result so far: 67780.0
If we subtract 0 from 568, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 9:
988 can be fit into 5680 5 times, resulting in a remainder of 740.
The next digit of our result is 5. 
Result so far: 67780.5
If we subtract 4940 from 5680, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 10:
988 can be fit into 7400 7 times, resulting in a remainder of 484.
Put 7 as the next digit of the answer. 
Result so far: 67780.57
If we take 6916 away from 7400, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 11:
The number 988 fits into 4840 4 times, leaving a remainder of 888.
The number 4 becomes the next digit in our result. 
Result so far: 67780.574
Deduct 3952 from 4840 and we're left with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Moving on to step 12:
If we divide 8880 by 988, we get 8 and a remainder of 976.
Put 8 as the next digit of the answer. 
Result so far: 67780.5748
Deduct 7904 from 8880 and we're left with 976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9760, and continue the process.

Moving on to step 13:
If we divide 9760 by 988, we get 9 and a remainder of 868.
Use 9 as the next digit of our solution. 
Result so far: 67780.57489
Subtracting 8892 from 9760 leaves us with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Going ahead to step 14:
If we divide 8680 by 988, we get 8 and a remainder of 776.
The number 8 becomes the next digit in our result. 
Result so far: 67780.574898
Subtract 7904 from 8680 to get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Step 15:
988 goes into 7760 7 times with a remainder of 844.
Record the quotient 7 as the next digit in the result. 
Result so far: 67780.5748987
Deduct 6916 from 7760 and we're left with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 16:
When dividing 8440 by 988, we get 8 with a remainder of 536.
The next digit of our result is 8. 
Result so far: 67780.57489878
The remainder is 536 after subtracting 7904 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Our division results in 67780.57489878 with a remaining 5.36e-07.
