7018283 ÷ 399 
We're looking to find how many times 399 goes into 7018283.

Moving on to step 1:
If we divide 7 by 399, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 399

Moving on to step 2:
If we divide 70 by 399, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 399

Let's proceed to step 3:
399 goes into 701 1 times with a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 399 from 701, we get 302.
Include the next digit (8) from the dividend after 302, then repeat: 3028 / 399

Moving on to step 4:
3028 divided by 399 is 7 with a remainder of 235.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 235 after subtracting 2793 from 3028.
Take the next digit (2) from the dividend and append it to 235, then repeat: 2352 / 399

Let's proceed to step 5:
2352 divided by 399 is 5 with a remainder of 357.
Write down 5 as next digit of the result. 
Result so far: 175.0
If we subtract 1995 from 2352, we get 357.
Grab the next digit (8) from the dividend, add it to 357, then carry on: 3578 / 399

Going ahead to step 6:
If we divide 3578 by 399, we get 8 and a remainder of 386.
Record the quotient 8 as the next digit in the result. 
Result so far: 1758.0
Subtract 3192 from 3578 to get 386.
Take the next digit (3) from the dividend and append it to 386, then repeat: 3863 / 399

Moving on to step 7:
The number 399 fits into 3863 9 times, leaving a remainder of 272.
The number 9 becomes the next digit in our result. 
Result so far: 17589.0
If we subtract 3591 from 3863, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 8:
The number 399 fits into 2720 6 times, leaving a remainder of 326.
The next digit of our result is 6. 
Result so far: 17589.6
If we subtract 2394 from 2720, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 9:
The number 399 fits into 3260 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 17589.68
Subtract 3192 from 3260 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
When dividing 680 by 399, we get 1 with a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 17589.681
Deduct 399 from 680 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 11:
When dividing 2810 by 399, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 17589.6817
Subtracting 2793 from 2810 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
399 goes into 170 0 times with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 17589.6817
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 13:
If we divide 1700 by 399, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 17589.681704
Subtract 1596 from 1700 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 14:
1040 divided by 399 is 2 with a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 17589.6817042
The remainder is 242 after subtracting 798 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 15:
The number 399 fits into 2420 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 17589.68170426
If we take 2394 away from 2420, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 17589.68170426, and the remainder is 2.6e-08.
