We're dividing 63981109 by 985 
The aim is to understand the frequency of 985 in 63981109.

Advancing to step 1:
When dividing 6 by 985, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 985

On to step 2:
985 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 985

Going ahead to step 3:
985 can be fit into 639 0 times, resulting in a remainder of 639.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 639 and we're left with 639.
Grab the next digit (8) from the dividend, add it to 639, then carry on: 6398 / 985

Advancing to step 4:
When dividing 6398 by 985, we get 6 with a remainder of 488.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 5910 away from 6398, we end up with 488.
Include the next digit (1) from the dividend after 488, then repeat: 4881 / 985

Step 5:
If we divide 4881 by 985, we get 4 and a remainder of 941.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 3940 from 4881 and we're left with 941.
Bring next digit (1) of the dividend behind the 941 and repeat the process: 9411 / 985

Moving on to step 6:
985 can be fit into 9411 9 times, resulting in a remainder of 546.
Write down 9 as next digit of the result. 
Result so far: 649.0
Deduct 8865 from 9411 and we're left with 546.
Include the next digit (0) from the dividend after 546, then repeat: 5460 / 985

Let's proceed to step 7:
985 goes into 5460 5 times with a remainder of 535.
The number 5 becomes the next digit in our result. 
Result so far: 6495.0
Subtract 4925 from 5460 to get 535.
Append the next digit (9) from the dividend to 535 and continue with: 5359 / 985

Moving on to step 8:
If we divide 5359 by 985, we get 5 and a remainder of 434.
Put 5 as the next digit of the answer. 
Result so far: 64955.0
Subtract 4925 from 5359 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 9:
4340 divided by 985 is 4 with a remainder of 400.
The next digit of our result is 4. 
Result so far: 64955.4
Subtract 3940 from 4340 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
If we divide 4000 by 985, we get 4 and a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 64955.44
If we take 3940 away from 4000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 64955.44 and a remainder of 0.06.
