64426551 divided by 985 
The aim is to understand the frequency of 985 in 64426551.

On to step 1:
The number 985 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 985

Moving on to step 2:
When dividing 64 by 985, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 985

Advancing to step 3:
When dividing 644 by 985, we get 0 with a remainder of 644.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 644, we get 644.
Include the next digit (2) from the dividend after 644, then repeat: 6442 / 985

Step 4:
If we divide 6442 by 985, we get 6 and a remainder of 532.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5910 from 6442 leaves us with 532.
Take the next digit (6) from the dividend and append it to 532, then repeat: 5326 / 985

Let's proceed to step 5:
If we divide 5326 by 985, we get 5 and a remainder of 401.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 401 after subtracting 4925 from 5326.
Grab the next digit (5) from the dividend, add it to 401, then carry on: 4015 / 985

Let's proceed to step 6:
When dividing 4015 by 985, we get 4 with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 654.0
Deduct 3940 from 4015 and we're left with 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 985

Advancing to step 7:
985 can be fit into 755 0 times, resulting in a remainder of 755.
Write down 0 as next digit of the result. 
Result so far: 6540.0
If we take 0 away from 755, we end up with 755.
Grab the next digit (1) from the dividend, add it to 755, then carry on: 7551 / 985

Let's proceed to step 8:
985 goes into 7551 7 times with a remainder of 656.
Put 7 as the next digit of the answer. 
Result so far: 65407.0
Subtracting 6895 from 7551 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 9:
985 goes into 6560 6 times with a remainder of 650.
The next digit of our result is 6. 
Result so far: 65407.6
The remainder is 650 after subtracting 5910 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 10:
The number 985 fits into 6500 6 times, leaving a remainder of 590.
Record the quotient 6 as the next digit in the result. 
Result so far: 65407.66
Subtract 5910 from 6500 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Our division results in 65407.66 with a remaining 0.59.
