Let's divide 3216173 by 851
The aim is to understand the frequency of 851 in 3216173.

Advancing to step 1:
When dividing 3 by 851, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 851

On to step 2:
851 goes into 32 0 times with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 851

Moving on to step 3:
851 can be fit into 321 0 times, resulting in a remainder of 321.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 321 to get 321.
Bring next digit (6) of the dividend behind the 321 and repeat the process: 3216 / 851

On to step 4:
The number 851 fits into 3216 3 times, leaving a remainder of 663.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2553 from 3216 leaves us with 663.
Take the next digit (1) from the dividend and append it to 663, then repeat: 6631 / 851

On to step 5:
851 can be fit into 6631 7 times, resulting in a remainder of 674.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 5957 from 6631 and we're left with 674.
Fetch the next digit (7) from the dividend, attach it to 674 and continue: 6747 / 851

Moving on to step 6:
The number 851 fits into 6747 7 times, leaving a remainder of 790.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we take 5957 away from 6747, we end up with 790.
Append the next digit (3) from the dividend to 790 and continue with: 7903 / 851

Advancing to step 7:
851 goes into 7903 9 times with a remainder of 244.
Put 9 as the next digit of the answer. 
Result so far: 3779.0
If we subtract 7659 from 7903, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 8:
2440 divided by 851 is 2 with a remainder of 738.
Record the quotient 2 as the next digit in the result. 
Result so far: 3779.2
Subtracting 1702 from 2440 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Step 9:
When dividing 7380 by 851, we get 8 with a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 3779.28
If we take 6808 away from 7380, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 10:
851 goes into 5720 6 times with a remainder of 614.
Write down 6 as next digit of the result. 
Result so far: 3779.286
Subtract 5106 from 5720 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 11:
The number 851 fits into 6140 7 times, leaving a remainder of 183.
Record the quotient 7 as the next digit in the result. 
Result so far: 3779.2867
If we take 5957 away from 6140, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 12:
If we divide 1830 by 851, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 3779.28672
Subtract 1702 from 1830 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
The number 851 fits into 1280 1 times, leaving a remainder of 429.
The next digit of our result is 1. 
Result so far: 3779.286721
The remainder is 429 after subtracting 851 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 14:
The number 851 fits into 4290 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3779.2867215
Subtract 4255 from 4290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 15:
If we divide 350 by 851, we get 0 and a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 3779.2867215
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final result is 3779.2867215 with a remainder of 3.5e-07.
