We divide 663999 by 93
We want to divide 663999 by 93.

Advancing to step 1:
When dividing 6 by 93, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 93

Moving on to step 2:
If we divide 66 by 93, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 93

Step 3:
663 divided by 93 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 651 from 663 to get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 93

Let's proceed to step 4:
93 can be fit into 129 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we take 93 away from 129, we end up with 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 93

Advancing to step 5:
369 divided by 93 is 3 with a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 713.0
Deduct 279 from 369 and we're left with 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 93

Advancing to step 6:
93 goes into 909 9 times with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 7139.0
Deduct 837 from 909 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
If we divide 720 by 93, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 7139.7
If we subtract 651 from 720, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 8:
690 divided by 93 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 7139.77
Subtract 651 from 690 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 7139.77, with a leftover of 0.039.
