We look at the division of 16730661 by 850 
The aim is to understand the frequency of 850 in 16730661.

Going ahead to step 1:
The number 850 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 850

Let's proceed to step 2:
If we divide 16 by 850, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 850

Step 3:
When dividing 167 by 850, we get 0 with a remainder of 167.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 167 and we're left with 167.
Fetch the next digit (3) from the dividend, attach it to 167 and continue: 1673 / 850

On to step 4:
850 goes into 1673 1 times with a remainder of 823.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 850 from 1673 leaves us with 823.
Bring next digit (0) of the dividend behind the 823 and repeat the process: 8230 / 850

Let's proceed to step 5:
When dividing 8230 by 850, we get 9 with a remainder of 580.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 7650 from 8230 and we're left with 580.
Take the next digit (6) from the dividend and append it to 580, then repeat: 5806 / 850

On to step 6:
If we divide 5806 by 850, we get 6 and a remainder of 706.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we take 5100 away from 5806, we end up with 706.
Fetch the next digit (6) from the dividend, attach it to 706 and continue: 7066 / 850

Step 7:
7066 divided by 850 is 8 with a remainder of 266.
Record the quotient 8 as the next digit in the result. 
Result so far: 1968.0
The remainder is 266 after subtracting 6800 from 7066.
Fetch the next digit (1) from the dividend, attach it to 266 and continue: 2661 / 850

Going ahead to step 8:
If we divide 2661 by 850, we get 3 and a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 19683.0
The remainder is 111 after subtracting 2550 from 2661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
1110 divided by 850 is 1 with a remainder of 260.
Write down 1 as next digit of the result. 
Result so far: 19683.1
The remainder is 260 after subtracting 850 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
2600 divided by 850 is 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 19683.13
Deduct 2550 from 2600 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
If we divide 500 by 850, we get 0 and a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 19683.13
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 12:
If we divide 5000 by 850, we get 5 and a remainder of 750.
The next digit of our result is 5. 
Result so far: 19683.1305
If we subtract 4250 from 5000, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 13:
The number 850 fits into 7500 8 times, leaving a remainder of 700.
Put 8 as the next digit of the answer. 
Result so far: 19683.13058
If we subtract 6800 from 7500, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 14:
7000 divided by 850 is 8 with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 19683.130588
Subtract 6800 from 7000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 19683.130588 with a remaining 2e-05.
