39786471 ÷ 929 
We want to figure out the number of times 39786471 can be divided by 929.

Step 1:
If we divide 3 by 929, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 929

Let's proceed to step 2:
929 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 929

Let's proceed to step 3:
If we divide 397 by 929, we get 0 and a remainder of 397.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 397 leaves us with 397.
Append the next digit (8) from the dividend to 397 and continue with: 3978 / 929

Moving on to step 4:
929 goes into 3978 4 times with a remainder of 262.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3716 from 3978 to get 262.
Append the next digit (6) from the dividend to 262 and continue with: 2626 / 929

On to step 5:
When dividing 2626 by 929, we get 2 with a remainder of 768.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 1858 from 2626 to get 768.
Grab the next digit (4) from the dividend, add it to 768, then carry on: 7684 / 929

Going ahead to step 6:
7684 divided by 929 is 8 with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 428.0
Subtract 7432 from 7684 to get 252.
Bring next digit (7) of the dividend behind the 252 and repeat the process: 2527 / 929

Moving on to step 7:
When dividing 2527 by 929, we get 2 with a remainder of 669.
The next digit of our result is 2. 
Result so far: 4282.0
Subtract 1858 from 2527 to get 669.
Grab the next digit (1) from the dividend, add it to 669, then carry on: 6691 / 929

Let's proceed to step 8:
929 can be fit into 6691 7 times, resulting in a remainder of 188.
Use 7 as the next digit of our solution. 
Result so far: 42827.0
If we subtract 6503 from 6691, we 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.

Advancing to step 9:
The number 929 fits into 1880 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 42827.2
The remainder is 22 after subtracting 1858 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
220 divided by 929 is 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 42827.2
If we subtract 0 from 220, 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 11:
929 goes into 2200 2 times with a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 42827.202
If we take 1858 away from 2200, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 12:
When dividing 3420 by 929, we get 3 with a remainder of 633.
The next digit of our result is 3. 
Result so far: 42827.2023
Subtracting 2787 from 3420 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.

Going ahead to step 13:
The number 929 fits into 6330 6 times, leaving a remainder of 756.
Put 6 as the next digit of the answer. 
Result so far: 42827.20236
If we subtract 5574 from 6330, we get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 14:
929 goes into 7560 8 times with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 42827.202368
If we subtract 7432 from 7560, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
The number 929 fits into 1280 1 times, leaving a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 42827.2023681
If we take 929 away from 1280, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 16:
929 goes into 3510 3 times with a remainder of 723.
Record the quotient 3 as the next digit in the result. 
Result so far: 42827.20236813
If we take 2787 away from 3510, we end up with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

The quotient of the division is 42827.20236813, and the remainder is 7.23e-07.
