39961478 ÷ 685 
We want to figure out the number of times 39961478 can be divided by 685.

Step 1:
When dividing 3 by 685, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 685

Advancing to step 2:
685 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 685

On to step 3:
399 divided by 685 is 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Grab the next digit (6) from the dividend, add it to 399, then carry on: 3996 / 685

Moving on to step 4:
685 goes into 3996 5 times with a remainder of 571.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3425 from 3996 to get 571.
Include the next digit (1) from the dividend after 571, then repeat: 5711 / 685

Going ahead to step 5:
When dividing 5711 by 685, we get 8 with a remainder of 231.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
The remainder is 231 after subtracting 5480 from 5711.
Grab the next digit (4) from the dividend, add it to 231, then carry on: 2314 / 685

Moving on to step 6:
When dividing 2314 by 685, we get 3 with a remainder of 259.
The number 3 becomes the next digit in our result. 
Result so far: 583.0
If we take 2055 away from 2314, we end up with 259.
Take the next digit (7) from the dividend and append it to 259, then repeat: 2597 / 685

Let's proceed to step 7:
685 can be fit into 2597 3 times, resulting in a remainder of 542.
Write down 3 as next digit of the result. 
Result so far: 5833.0
If we subtract 2055 from 2597, we get 542.
Bring next digit (8) of the dividend behind the 542 and repeat the process: 5428 / 685

Going ahead to step 8:
If we divide 5428 by 685, we get 7 and a remainder of 633.
Record the quotient 7 as the next digit in the result. 
Result so far: 58337.0
Subtracting 4795 from 5428 leaves us with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Moving on to step 9:
When dividing 6330 by 685, we get 9 with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 58337.9
The remainder is 165 after subtracting 6165 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
685 goes into 1650 2 times with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 58337.92
The remainder is 280 after subtracting 1370 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
If we divide 2800 by 685, we get 4 and a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 58337.924
If we subtract 2740 from 2800, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
685 goes into 600 0 times with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 58337.924
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
685 can be fit into 6000 8 times, resulting in a remainder of 520.
The next digit of our result is 8. 
Result so far: 58337.92408
The remainder is 520 after subtracting 5480 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 14:
If we divide 5200 by 685, we get 7 and a remainder of 405.
Record the quotient 7 as the next digit in the result. 
Result so far: 58337.924087
The remainder is 405 after subtracting 4795 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 15:
If we divide 4050 by 685, we get 5 and a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 58337.9240875
The remainder is 625 after subtracting 3425 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 16:
If we divide 6250 by 685, we get 9 and a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 58337.92408759
If we take 6165 away from 6250, we end up 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.

Our division results in 58337.92408759 with a remaining 8.5e-08.
