16908926 ÷ 644 
We're looking to find how many times 644 goes into 16908926.

Moving on to step 1:
1 divided by 644 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 644

Let's proceed to step 2:
644 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 644

Advancing to step 3:
The number 644 fits into 169 0 times, leaving a remainder of 169.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 169, we get 169.
Take the next digit (0) from the dividend and append it to 169, then repeat: 1690 / 644

Advancing to step 4:
1690 divided by 644 is 2 with a remainder of 402.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1288 away from 1690, we end up with 402.
Bring next digit (8) of the dividend behind the 402 and repeat the process: 4028 / 644

Step 5:
644 can be fit into 4028 6 times, resulting in a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 164 after subtracting 3864 from 4028.
Take the next digit (9) from the dividend and append it to 164, then repeat: 1649 / 644

Going ahead to step 6:
When dividing 1649 by 644, we get 2 with a remainder of 361.
Use 2 as the next digit of our solution. 
Result so far: 262.0
Subtracting 1288 from 1649 leaves us with 361.
Grab the next digit (2) from the dividend, add it to 361, then carry on: 3612 / 644

On to step 7:
If we divide 3612 by 644, we get 5 and a remainder of 392.
The next digit of our result is 5. 
Result so far: 2625.0
The remainder is 392 after subtracting 3220 from 3612.
Fetch the next digit (6) from the dividend, attach it to 392 and continue: 3926 / 644

Let's proceed to step 8:
The number 644 fits into 3926 6 times, leaving a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 26256.0
Subtracting 3864 from 3926 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
644 goes into 620 0 times with a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 26256.0
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
When dividing 6200 by 644, we get 9 with a remainder of 404.
The next digit of our result is 9. 
Result so far: 26256.09
Deduct 5796 from 6200 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 11:
If we divide 4040 by 644, we get 6 and a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 26256.096
If we take 3864 away from 4040, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 12:
1760 divided by 644 is 2 with a remainder of 472.
Write down 2 as next digit of the result. 
Result so far: 26256.0962
Subtract 1288 from 1760 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 13:
4720 divided by 644 is 7 with a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 26256.09627
The remainder is 212 after subtracting 4508 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 14:
644 can be fit into 2120 3 times, resulting in a remainder of 188.
Use 3 as the next digit of our solution. 
Result so far: 26256.096273
Subtract 1932 from 2120 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 15:
If we divide 1880 by 644, we get 2 and a remainder of 592.
Put 2 as the next digit of the answer. 
Result so far: 26256.0962732
If we take 1288 away from 1880, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 16:
When dividing 5920 by 644, we get 9 with a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 26256.09627329
Subtracting 5796 from 5920 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

In conclusion, the division gives 26256.09627329 with a balance of 1.24e-07.
