39949802 ÷ 905 
We're looking to find how many times 905 goes into 39949802.

Moving on to step 1:
905 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 905

Moving on to step 2:
If we divide 39 by 905, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 905

Advancing to step 3:
When dividing 399 by 905, we get 0 with a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Grab the next digit (4) from the dividend, add it to 399, then carry on: 3994 / 905

On to step 4:
When dividing 3994 by 905, we get 4 with a remainder of 374.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3620 away from 3994, we end up with 374.
Fetch the next digit (9) from the dividend, attach it to 374 and continue: 3749 / 905

Step 5:
3749 divided by 905 is 4 with a remainder of 129.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 3620 from 3749 and we're left with 129.
Take the next digit (8) from the dividend and append it to 129, then repeat: 1298 / 905

Advancing to step 6:
When dividing 1298 by 905, we get 1 with a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 441.0
If we subtract 905 from 1298, we get 393.
Fetch the next digit (0) from the dividend, attach it to 393 and continue: 3930 / 905

Let's proceed to step 7:
The number 905 fits into 3930 4 times, leaving a remainder of 310.
Put 4 as the next digit of the answer. 
Result so far: 4414.0
Subtracting 3620 from 3930 leaves us with 310.
Append the next digit (2) from the dividend to 310 and continue with: 3102 / 905

On to step 8:
The number 905 fits into 3102 3 times, leaving a remainder of 387.
Write down 3 as next digit of the result. 
Result so far: 44143.0
Subtract 2715 from 3102 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 9:
When dividing 3870 by 905, we get 4 with a remainder of 250.
Write down 4 as next digit of the result. 
Result so far: 44143.4
If we take 3620 away from 3870, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
When dividing 2500 by 905, we get 2 with a remainder of 690.
The next digit of our result is 2. 
Result so far: 44143.42
Subtract 1810 from 2500 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 11:
When dividing 6900 by 905, we get 7 with a remainder of 565.
Write down 7 as next digit of the result. 
Result so far: 44143.427
Subtracting 6335 from 6900 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

On to step 12:
The number 905 fits into 5650 6 times, leaving a remainder of 220.
Write down 6 as next digit of the result. 
Result so far: 44143.4276
If we subtract 5430 from 5650, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
905 goes into 2200 2 times with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 44143.42762
Deduct 1810 from 2200 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 14:
If we divide 3900 by 905, we get 4 and a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 44143.427624
Subtract 3620 from 3900 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
905 can be fit into 2800 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 44143.4276243
Deduct 2715 from 2800 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 16:
850 divided by 905 is 0 with a remainder of 850.
Write down 0 as next digit of the result. 
Result so far: 44143.4276243
If we subtract 0 from 850, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

In conclusion, the division gives 44143.4276243 with a balance of 8.5e-07.
