64108105 ÷ 851 
The aim is to understand the frequency of 851 in 64108105.

Let's proceed to step 1:
851 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 851

Step 2:
When dividing 64 by 851, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 851

Moving on to step 3:
The number 851 fits into 641 0 times, leaving a remainder of 641.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 641 leaves us with 641.
Grab the next digit (0) from the dividend, add it to 641, then carry on: 6410 / 851

Advancing to step 4:
851 goes into 6410 7 times with a remainder of 453.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 453 after subtracting 5957 from 6410.
Bring next digit (8) of the dividend behind the 453 and repeat the process: 4538 / 851

Going ahead to step 5:
851 goes into 4538 5 times with a remainder of 283.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 283 after subtracting 4255 from 4538.
Fetch the next digit (1) from the dividend, attach it to 283 and continue: 2831 / 851

On to step 6:
851 goes into 2831 3 times with a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 753.0
Subtracting 2553 from 2831 leaves us with 278.
Include the next digit (0) from the dividend after 278, then repeat: 2780 / 851

On to step 7:
If we divide 2780 by 851, we get 3 and a remainder of 227.
Use 3 as the next digit of our solution. 
Result so far: 7533.0
Deduct 2553 from 2780 and we're left with 227.
Take the next digit (5) from the dividend and append it to 227, then repeat: 2275 / 851

Step 8:
If we divide 2275 by 851, we get 2 and a remainder of 573.
Put 2 as the next digit of the answer. 
Result so far: 75332.0
Subtracting 1702 from 2275 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 9:
The number 851 fits into 5730 6 times, leaving a remainder of 624.
Record the quotient 6 as the next digit in the result. 
Result so far: 75332.6
If we take 5106 away from 5730, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 10:
If we divide 6240 by 851, we get 7 and a remainder of 283.
The next digit of our result is 7. 
Result so far: 75332.67
If we take 5957 away from 6240, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 11:
If we divide 2830 by 851, we get 3 and a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 75332.673
The remainder is 277 after subtracting 2553 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 12:
The number 851 fits into 2770 3 times, leaving a remainder of 217.
Record the quotient 3 as the next digit in the result. 
Result so far: 75332.6733
If we take 2553 away from 2770, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

The final outcome is 75332.6733, with a leftover of 0.00217.
