Let's divide 46358391 by 390
We're looking to find how many times 390 goes into 46358391.

On to step 1:
4 divided by 390 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 390

Step 2:
If we divide 46 by 390, we get 0 and a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 390

Moving on to step 3:
If we divide 463 by 390, we get 1 and a remainder of 73.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 73 after subtracting 390 from 463.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 390

Advancing to step 4:
390 can be fit into 735 1 times, resulting in a remainder of 345.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 390 from 735 leaves us with 345.
Grab the next digit (8) from the dividend, add it to 345, then carry on: 3458 / 390

Going ahead to step 5:
The number 390 fits into 3458 8 times, leaving a remainder of 338.
Write down 8 as next digit of the result. 
Result so far: 118.0
If we subtract 3120 from 3458, we get 338.
Fetch the next digit (3) from the dividend, attach it to 338 and continue: 3383 / 390

Step 6:
3383 divided by 390 is 8 with a remainder of 263.
The next digit of our result is 8. 
Result so far: 1188.0
If we take 3120 away from 3383, we end up with 263.
Take the next digit (9) from the dividend and append it to 263, then repeat: 2639 / 390

Advancing to step 7:
The number 390 fits into 2639 6 times, leaving a remainder of 299.
The next digit of our result is 6. 
Result so far: 11886.0
The remainder is 299 after subtracting 2340 from 2639.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 390

Step 8:
390 goes into 2991 7 times with a remainder of 261.
The next digit of our result is 7. 
Result so far: 118867.0
Subtract 2730 from 2991 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 9:
390 can be fit into 2610 6 times, resulting in a remainder of 270.
Put 6 as the next digit of the answer. 
Result so far: 118867.6
If we take 2340 away from 2610, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
When dividing 2700 by 390, we get 6 with a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 118867.66
Subtracting 2340 from 2700 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 118867.66 and a remainder of 0.36.
