We divide 39979606 by 405
We want to figure out the number of times 39979606 can be divided by 405.

Going ahead to step 1:
405 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 405

Going ahead to step 2:
39 divided by 405 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 405

Moving on to step 3:
The number 405 fits into 399 0 times, leaving a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Bring next digit (7) of the dividend behind the 399 and repeat the process: 3997 / 405

Advancing to step 4:
3997 divided by 405 is 9 with a remainder of 352.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3645 away from 3997, we end up with 352.
Grab the next digit (9) from the dividend, add it to 352, then carry on: 3529 / 405

Going ahead to step 5:
When dividing 3529 by 405, we get 8 with a remainder of 289.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtract 3240 from 3529 to get 289.
Bring next digit (6) of the dividend behind the 289 and repeat the process: 2896 / 405

Advancing to step 6:
2896 divided by 405 is 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 987.0
If we take 2835 away from 2896, we end up with 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 405

Going ahead to step 7:
405 can be fit into 610 1 times, resulting in a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 9871.0
Subtracting 405 from 610 leaves us with 205.
Bring next digit (6) of the dividend behind the 205 and repeat the process: 2056 / 405

Let's proceed to step 8:
405 can be fit into 2056 5 times, resulting in a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 98715.0
The remainder is 31 after subtracting 2025 from 2056.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
The number 405 fits into 310 0 times, leaving a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 98715.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
When dividing 3100 by 405, we get 7 with a remainder of 265.
The next digit of our result is 7. 
Result so far: 98715.07
The remainder is 265 after subtracting 2835 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 11:
405 can be fit into 2650 6 times, resulting in a remainder of 220.
The next digit of our result is 6. 
Result so far: 98715.076
If we subtract 2430 from 2650, 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.

Advancing to step 12:
The number 405 fits into 2200 5 times, leaving a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 98715.0765
The remainder is 175 after subtracting 2025 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
405 goes into 1750 4 times with a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 98715.07654
The remainder is 130 after subtracting 1620 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
If we divide 1300 by 405, we get 3 and a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 98715.076543
Subtracting 1215 from 1300 leaves us 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.

Let's proceed to step 15:
When dividing 850 by 405, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 98715.0765432
If we take 810 away from 850, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
The number 405 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 98715.0765432
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 98715.0765432 with a remainder of 4e-07.
