We divide 15859685 by 622
We want to figure out the number of times 15859685 can be divided by 622.

Moving on to step 1:
If we divide 1 by 622, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 622

Going ahead to step 2:
15 divided by 622 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 622

Moving on to step 3:
622 goes into 158 0 times with 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.
Fetch the next digit (5) from the dividend, attach it to 158 and continue: 1585 / 622

Going ahead to step 4:
622 can be fit into 1585 2 times, resulting in a remainder of 341.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1244 from 1585 and we're left with 341.
Include the next digit (9) from the dividend after 341, then repeat: 3419 / 622

Going ahead to step 5:
622 goes into 3419 5 times with a remainder of 309.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 3110 from 3419 to get 309.
Append the next digit (6) from the dividend to 309 and continue with: 3096 / 622

Let's proceed to step 6:
622 goes into 3096 4 times with a remainder of 608.
Write down 4 as next digit of the result. 
Result so far: 254.0
The remainder is 608 after subtracting 2488 from 3096.
Append the next digit (8) from the dividend to 608 and continue with: 6088 / 622

Going ahead to step 7:
The number 622 fits into 6088 9 times, leaving a remainder of 490.
The next digit of our result is 9. 
Result so far: 2549.0
If we subtract 5598 from 6088, we get 490.
Include the next digit (5) from the dividend after 490, then repeat: 4905 / 622

Step 8:
4905 divided by 622 is 7 with a remainder of 551.
Put 7 as the next digit of the answer. 
Result so far: 25497.0
If we subtract 4354 from 4905, we get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 9:
5510 divided by 622 is 8 with a remainder of 534.
Use 8 as the next digit of our solution. 
Result so far: 25497.8
If we subtract 4976 from 5510, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 10:
622 can be fit into 5340 8 times, resulting in a remainder of 364.
Write down 8 as next digit of the result. 
Result so far: 25497.88
The remainder is 364 after subtracting 4976 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 25497.88 with a remainder of 0.364.
