78941997 divided by 988 
The aim is to understand the frequency of 988 in 78941997.

Going ahead to step 1:
When dividing 7 by 988, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 988

On to step 2:
78 divided by 988 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 988

Let's proceed to step 3:
If we divide 789 by 988, we get 0 and a remainder of 789.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 789 and we're left with 789.
Fetch the next digit (4) from the dividend, attach it to 789 and continue: 7894 / 988

Advancing to step 4:
7894 divided by 988 is 7 with a remainder of 978.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6916 from 7894 and we're left with 978.
Grab the next digit (1) from the dividend, add it to 978, then carry on: 9781 / 988

Step 5:
9781 divided by 988 is 9 with a remainder of 889.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 8892 from 9781 to get 889.
Take the next digit (9) from the dividend and append it to 889, then repeat: 8899 / 988

Step 6:
When dividing 8899 by 988, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
Deduct 8892 from 8899 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 988

Step 7:
988 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 7990.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 988

Step 8:
988 goes into 797 0 times with a remainder of 797.
Use 0 as the next digit of our solution. 
Result so far: 79900.0
If we take 0 away from 797, we end up with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Let's proceed to step 9:
If we divide 7970 by 988, we get 8 and a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 79900.8
Subtracting 7904 from 7970 leaves us 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.

Advancing to step 10:
If we divide 660 by 988, we get 0 and a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 79900.8
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 11:
When dividing 6600 by 988, we get 6 with a remainder of 672.
The next digit of our result is 6. 
Result so far: 79900.806
If we take 5928 away from 6600, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 12:
988 goes into 6720 6 times with a remainder of 792.
Put 6 as the next digit of the answer. 
Result so far: 79900.8066
If we take 5928 away from 6720, we end up with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

The final outcome is 79900.8066, with a leftover of 0.00792.
