We look at the division of 16166451 by 622 
We want to figure out the number of times 16166451 can be divided by 622.

Going ahead to step 1:
If we divide 1 by 622, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 622

Advancing to step 2:
If we divide 16 by 622, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 622

Going ahead to step 3:
The number 622 fits into 161 0 times, leaving a remainder of 161.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Bring next digit (6) of the dividend behind the 161 and repeat the process: 1616 / 622

Let's proceed to step 4:
When dividing 1616 by 622, we get 2 with a remainder of 372.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1244 from 1616, we get 372.
Fetch the next digit (6) from the dividend, attach it to 372 and continue: 3726 / 622

Going ahead to step 5:
The number 622 fits into 3726 5 times, leaving a remainder of 616.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 3110 away from 3726, we end up with 616.
Grab the next digit (4) from the dividend, add it to 616, then carry on: 6164 / 622

Moving on to step 6:
6164 divided by 622 is 9 with a remainder of 566.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Subtracting 5598 from 6164 leaves us with 566.
Fetch the next digit (5) from the dividend, attach it to 566 and continue: 5665 / 622

Let's proceed to step 7:
5665 divided by 622 is 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 2599.0
The remainder is 67 after subtracting 5598 from 5665.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 622

Moving on to step 8:
671 divided by 622 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 25991.0
If we take 622 away from 671, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
490 divided by 622 is 0 with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 25991.0
Subtracting 0 from 490 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 10:
When dividing 4900 by 622, we get 7 with a remainder of 546.
The next digit of our result is 7. 
Result so far: 25991.07
The remainder is 546 after subtracting 4354 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 11:
When dividing 5460 by 622, we get 8 with a remainder of 484.
Write down 8 as next digit of the result. 
Result so far: 25991.078
If we take 4976 away from 5460, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 12:
622 can be fit into 4840 7 times, resulting in a remainder of 486.
Put 7 as the next digit of the answer. 
Result so far: 25991.0787
Subtract 4354 from 4840 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 13:
The number 622 fits into 4860 7 times, leaving a remainder of 506.
The number 7 becomes the next digit in our result. 
Result so far: 25991.07877
Deduct 4354 from 4860 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The quotient of the division is 25991.07877, and the remainder is 0.000506.
