4170494 ÷ 394 
We want to figure out the number of times 4170494 can be divided by 394.

On to step 1:
394 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 394

Let's proceed to step 2:
41 divided by 394 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 394

Let's proceed to step 3:
417 divided by 394 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 394 from 417 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 394

Step 4:
394 goes into 230 0 times with a remainder of 230.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 230 leaves us with 230.
Take the next digit (4) from the dividend and append it to 230, then repeat: 2304 / 394

On to step 5:
394 goes into 2304 5 times with a remainder of 334.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we subtract 1970 from 2304, we get 334.
Fetch the next digit (9) from the dividend, attach it to 334 and continue: 3349 / 394

On to step 6:
3349 divided by 394 is 8 with a remainder of 197.
Write down 8 as next digit of the result. 
Result so far: 1058.0
Subtract 3152 from 3349 to get 197.
Take the next digit (4) from the dividend and append it to 197, then repeat: 1974 / 394

Advancing to step 7:
The number 394 fits into 1974 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 10585.0
Subtracting 1970 from 1974 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
394 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10585.0
If we take 0 away from 40, 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.

On to step 9:
394 can be fit into 400 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 10585.01
Subtracting 394 from 400 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
394 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10585.01
Subtract 0 from 60 to 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.

Let's proceed to step 11:
394 can be fit into 600 1 times, resulting in a remainder of 206.
Record the quotient 1 as the next digit in the result. 
Result so far: 10585.0101
The remainder is 206 after subtracting 394 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 12:
394 can be fit into 2060 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 10585.01015
Deduct 1970 from 2060 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
When dividing 900 by 394, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 10585.010152
Subtract 788 from 900 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
394 goes into 1120 2 times with a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 10585.0101522
If we subtract 788 from 1120, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final result is 10585.0101522 with a remainder of 3.32e-06.
