We look at the division of 70733293 by 399 
Let's see how many times 399 fits into 70733293.

On to step 1:
The number 399 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 399

Step 2:
The number 399 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 399

Going ahead to step 3:
The number 399 fits into 707 1 times, leaving a remainder of 308.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 399 from 707 to get 308.
Include the next digit (3) from the dividend after 308, then repeat: 3083 / 399

Going ahead to step 4:
If we divide 3083 by 399, we get 7 and a remainder of 290.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 2793 from 3083 leaves us with 290.
Fetch the next digit (3) from the dividend, attach it to 290 and continue: 2903 / 399

Step 5:
When dividing 2903 by 399, we get 7 with a remainder of 110.
Use 7 as the next digit of our solution. 
Result so far: 177.0
Subtracting 2793 from 2903 leaves us with 110.
Bring next digit (2) of the dividend behind the 110 and repeat the process: 1102 / 399

Moving on to step 6:
The number 399 fits into 1102 2 times, leaving a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 1772.0
Subtracting 798 from 1102 leaves us with 304.
Bring next digit (9) of the dividend behind the 304 and repeat the process: 3049 / 399

Moving on to step 7:
399 can be fit into 3049 7 times, resulting in a remainder of 256.
The number 7 becomes the next digit in our result. 
Result so far: 17727.0
If we subtract 2793 from 3049, we get 256.
Append the next digit (3) from the dividend to 256 and continue with: 2563 / 399

On to step 8:
399 goes into 2563 6 times with a remainder of 169.
Use 6 as the next digit of our solution. 
Result so far: 177276.0
Subtracting 2394 from 2563 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 9:
399 can be fit into 1690 4 times, resulting in a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 177276.4
The remainder is 94 after subtracting 1596 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
940 divided by 399 is 2 with a remainder of 142.
Write down 2 as next digit of the result. 
Result so far: 177276.42
If we subtract 798 from 940, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 11:
399 can be fit into 1420 3 times, resulting in a remainder of 223.
Use 3 as the next digit of our solution. 
Result so far: 177276.423
Deduct 1197 from 1420 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 12:
399 can be fit into 2230 5 times, resulting in a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 177276.4235
The remainder is 235 after subtracting 1995 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 13:
399 can be fit into 2350 5 times, resulting in a remainder of 355.
Write down 5 as next digit of the result. 
Result so far: 177276.42355
Deduct 1995 from 2350 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The quotient of the division is 177276.42355, and the remainder is 0.000355.
