3929891 divided by 917 
We're looking to find how many times 917 goes into 3929891.

On to step 1:
If we divide 3 by 917, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 917

Going ahead to step 2:
The number 917 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 917

Advancing to step 3:
If we divide 392 by 917, we get 0 and a remainder of 392.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 392 to get 392.
Grab the next digit (9) from the dividend, add it to 392, then carry on: 3929 / 917

On to step 4:
The number 917 fits into 3929 4 times, leaving a remainder of 261.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3668 from 3929 to get 261.
Include the next digit (8) from the dividend after 261, then repeat: 2618 / 917

Advancing to step 5:
917 goes into 2618 2 times with a remainder of 784.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 1834 from 2618 and we're left with 784.
Take the next digit (9) from the dividend and append it to 784, then repeat: 7849 / 917

Step 6:
If we divide 7849 by 917, we get 8 and a remainder of 513.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
Subtract 7336 from 7849 to get 513.
Take the next digit (1) from the dividend and append it to 513, then repeat: 5131 / 917

Let's proceed to step 7:
The number 917 fits into 5131 5 times, leaving a remainder of 546.
The number 5 becomes the next digit in our result. 
Result so far: 4285.0
Subtract 4585 from 5131 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 8:
917 can be fit into 5460 5 times, resulting in a remainder of 875.
The number 5 becomes the next digit in our result. 
Result so far: 4285.5
If we take 4585 away from 5460, we end up with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Let's proceed to step 9:
When dividing 8750 by 917, we get 9 with a remainder of 497.
Record the quotient 9 as the next digit in the result. 
Result so far: 4285.59
Subtract 8253 from 8750 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 10:
4970 divided by 917 is 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 4285.595
If we take 4585 away from 4970, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 11:
917 goes into 3850 4 times with a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 4285.5954
The remainder is 182 after subtracting 3668 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 12:
When dividing 1820 by 917, we get 1 with a remainder of 903.
Use 1 as the next digit of our solution. 
Result so far: 4285.59541
Subtract 917 from 1820 to get 903.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9030, and continue the process.

Let's proceed to step 13:
9030 divided by 917 is 9 with a remainder of 777.
Record the quotient 9 as the next digit in the result. 
Result so far: 4285.595419
Deduct 8253 from 9030 and we're left with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

On to step 14:
917 can be fit into 7770 8 times, resulting in a remainder of 434.
Record the quotient 8 as the next digit in the result. 
Result so far: 4285.5954198
The remainder is 434 after subtracting 7336 from 7770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 15:
The number 917 fits into 4340 4 times, leaving a remainder of 672.
Record the quotient 4 as the next digit in the result. 
Result so far: 4285.59541984
If we subtract 3668 from 4340, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The quotient of the division is 4285.59541984, and the remainder is 6.72e-07.
