64080579 divided by 988 
The aim is to understand the frequency of 988 in 64080579.

Going ahead to step 1:
If we divide 6 by 988, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 988

Going ahead to step 2:
988 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 988

On to step 3:
988 can be fit into 640 0 times, resulting in a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 640 to get 640.
Bring next digit (8) of the dividend behind the 640 and repeat the process: 6408 / 988

Let's proceed to step 4:
The number 988 fits into 6408 6 times, leaving a remainder of 480.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5928 from 6408 to get 480.
Grab the next digit (0) from the dividend, add it to 480, then carry on: 4800 / 988

Let's proceed to step 5:
If we divide 4800 by 988, we get 4 and a remainder of 848.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 3952 from 4800 leaves us with 848.
Take the next digit (5) from the dividend and append it to 848, then repeat: 8485 / 988

Moving on to step 6:
If we divide 8485 by 988, we get 8 and a remainder of 581.
Record the quotient 8 as the next digit in the result. 
Result so far: 648.0
Subtract 7904 from 8485 to get 581.
Bring next digit (7) of the dividend behind the 581 and repeat the process: 5817 / 988

Let's proceed to step 7:
When dividing 5817 by 988, we get 5 with a remainder of 877.
Record the quotient 5 as the next digit in the result. 
Result so far: 6485.0
If we take 4940 away from 5817, we end up with 877.
Append the next digit (9) from the dividend to 877 and continue with: 8779 / 988

Step 8:
8779 divided by 988 is 8 with a remainder of 875.
Use 8 as the next digit of our solution. 
Result so far: 64858.0
Deduct 7904 from 8779 and we're left with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Advancing to step 9:
988 goes into 8750 8 times with a remainder of 846.
The number 8 becomes the next digit in our result. 
Result so far: 64858.8
The remainder is 846 after subtracting 7904 from 8750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Step 10:
988 can be fit into 8460 8 times, resulting in a remainder of 556.
The number 8 becomes the next digit in our result. 
Result so far: 64858.88
If we take 7904 away from 8460, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Our division results in 64858.88 with a remaining 0.556.
