We divide 15815967 by 622
We want to divide 15815967 by 622.

Going ahead to step 1:
The number 622 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 622

Advancing to step 2:
622 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 622

Step 3:
If we divide 158 by 622, we get 0 and a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Bring next digit (1) of the dividend behind the 158 and repeat the process: 1581 / 622

Going ahead to step 4:
When dividing 1581 by 622, we get 2 with a remainder of 337.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1244 from 1581 leaves us with 337.
Bring next digit (5) of the dividend behind the 337 and repeat the process: 3375 / 622

Moving on to step 5:
When dividing 3375 by 622, we get 5 with a remainder of 265.
The next digit of our result is 5. 
Result so far: 25.0
If we take 3110 away from 3375, we end up with 265.
Take the next digit (9) from the dividend and append it to 265, then repeat: 2659 / 622

On to step 6:
2659 divided by 622 is 4 with a remainder of 171.
Put 4 as the next digit of the answer. 
Result so far: 254.0
If we take 2488 away from 2659, we end up with 171.
Grab the next digit (6) from the dividend, add it to 171, then carry on: 1716 / 622

On to step 7:
When dividing 1716 by 622, we get 2 with a remainder of 472.
The number 2 becomes the next digit in our result. 
Result so far: 2542.0
If we take 1244 away from 1716, we end up with 472.
Fetch the next digit (7) from the dividend, attach it to 472 and continue: 4727 / 622

Let's proceed to step 8:
4727 divided by 622 is 7 with a remainder of 373.
Use 7 as the next digit of our solution. 
Result so far: 25427.0
Subtracting 4354 from 4727 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 9:
622 goes into 3730 5 times with a remainder of 620.
Record the quotient 5 as the next digit in the result. 
Result so far: 25427.5
Subtracting 3110 from 3730 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
622 can be fit into 6200 9 times, resulting in a remainder of 602.
Write down 9 as next digit of the result. 
Result so far: 25427.59
If we subtract 5598 from 6200, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 11:
622 can be fit into 6020 9 times, resulting in a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 25427.599
If we subtract 5598 from 6020, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

In conclusion, the division gives 25427.599 with a balance of 0.0422.
