16173541 divided by 806 
The aim is to understand the frequency of 806 in 16173541.

Advancing to step 1:
If we divide 1 by 806, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 806

Step 2:
When dividing 16 by 806, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 806

Advancing to step 3:
806 can be fit into 161 0 times, resulting in a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 806

Going ahead to step 4:
The number 806 fits into 1617 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1612 from 1617 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 806

Step 5:
The number 806 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 806

Step 6:
When dividing 535 by 806, we get 0 with a remainder of 535.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Deduct 0 from 535 and we're left with 535.
Grab the next digit (4) from the dividend, add it to 535, then carry on: 5354 / 806

Going ahead to step 7:
When dividing 5354 by 806, we get 6 with a remainder of 518.
Write down 6 as next digit of the result. 
Result so far: 2006.0
The remainder is 518 after subtracting 4836 from 5354.
Append the next digit (1) from the dividend to 518 and continue with: 5181 / 806

Going ahead to step 8:
806 can be fit into 5181 6 times, resulting in a remainder of 345.
The next digit of our result is 6. 
Result so far: 20066.0
Subtract 4836 from 5181 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
When dividing 3450 by 806, we get 4 with a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 20066.4
Deduct 3224 from 3450 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
806 goes into 2260 2 times with a remainder of 648.
Use 2 as the next digit of our solution. 
Result so far: 20066.42
If we take 1612 away from 2260, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 11:
When dividing 6480 by 806, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 20066.428
If we take 6448 away from 6480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
806 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 20066.428
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
The number 806 fits into 3200 3 times, leaving a remainder of 782.
Record the quotient 3 as the next digit in the result. 
Result so far: 20066.42803
Subtract 2418 from 3200 to get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Let's proceed to step 14:
806 can be fit into 7820 9 times, resulting in a remainder of 566.
The number 9 becomes the next digit in our result. 
Result so far: 20066.428039
Subtracting 7254 from 7820 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 15:
806 can be fit into 5660 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 20066.4280397
Subtract 5642 from 5660 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
806 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 20066.4280397
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 20066.4280397 and a remainder of 1.8e-07.
