39638146 ÷ 908 
Our goal is to divide 39638146 by 908.

Let's proceed to step 1:
3 divided by 908 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 908

Moving on to step 2:
When dividing 39 by 908, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 908

Moving on to step 3:
396 divided by 908 is 0 with a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.
Grab the next digit (3) from the dividend, add it to 396, then carry on: 3963 / 908

Advancing to step 4:
908 can be fit into 3963 4 times, resulting in a remainder of 331.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3632 away from 3963, we end up with 331.
Bring next digit (8) of the dividend behind the 331 and repeat the process: 3318 / 908

On to step 5:
908 can be fit into 3318 3 times, resulting in a remainder of 594.
The next digit of our result is 3. 
Result so far: 43.0
If we take 2724 away from 3318, we end up with 594.
Take the next digit (1) from the dividend and append it to 594, then repeat: 5941 / 908

Let's proceed to step 6:
When dividing 5941 by 908, we get 6 with a remainder of 493.
Use 6 as the next digit of our solution. 
Result so far: 436.0
Subtract 5448 from 5941 to get 493.
Fetch the next digit (4) from the dividend, attach it to 493 and continue: 4934 / 908

Advancing to step 7:
4934 divided by 908 is 5 with a remainder of 394.
Use 5 as the next digit of our solution. 
Result so far: 4365.0
If we subtract 4540 from 4934, we get 394.
Bring next digit (6) of the dividend behind the 394 and repeat the process: 3946 / 908

On to step 8:
The number 908 fits into 3946 4 times, leaving a remainder of 314.
Write down 4 as next digit of the result. 
Result so far: 43654.0
Subtract 3632 from 3946 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 9:
908 goes into 3140 3 times with a remainder of 416.
Record the quotient 3 as the next digit in the result. 
Result so far: 43654.3
Deduct 2724 from 3140 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 10:
908 can be fit into 4160 4 times, resulting in a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 43654.34
If we take 3632 away from 4160, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 11:
If we divide 5280 by 908, we get 5 and a remainder of 740.
The number 5 becomes the next digit in our result. 
Result so far: 43654.345
The remainder is 740 after subtracting 4540 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 12:
When dividing 7400 by 908, we get 8 with a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 43654.3458
If we take 7264 away from 7400, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
The number 908 fits into 1360 1 times, leaving a remainder of 452.
Put 1 as the next digit of the answer. 
Result so far: 43654.34581
Subtracting 908 from 1360 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 14:
If we divide 4520 by 908, we get 4 and a remainder of 888.
The next digit of our result is 4. 
Result so far: 43654.345814
Deduct 3632 from 4520 and we're left with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

On to step 15:
The number 908 fits into 8880 9 times, leaving a remainder of 708.
The number 9 becomes the next digit in our result. 
Result so far: 43654.3458149
Subtract 8172 from 8880 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Going ahead to step 16:
If we divide 7080 by 908, we get 7 and a remainder of 724.
Use 7 as the next digit of our solution. 
Result so far: 43654.34581497
Subtracting 6356 from 7080 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

The final result is 43654.34581497 with a remainder of 7.24e-07.
