We look at the division of 63403459 by 893 
Let's see how many times 893 fits into 63403459.

Let's proceed to step 1:
When dividing 6 by 893, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 893

Going ahead to step 2:
63 divided by 893 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 893

Going ahead to step 3:
893 goes into 634 0 times with a remainder of 634.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 634 after subtracting 0 from 634.
Grab the next digit (0) from the dividend, add it to 634, then carry on: 6340 / 893

Going ahead to step 4:
The number 893 fits into 6340 7 times, leaving a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6251 from 6340 leaves us with 89.
Bring next digit (3) of the dividend behind the 89 and repeat the process: 893 / 893

On to step 5:
If we divide 893 by 893, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 893 from 893 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 893

Going ahead to step 6:
The number 893 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 710.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 893

Let's proceed to step 7:
893 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 7100.0
If we subtract 0 from 45, we get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 893

Moving on to step 8:
459 divided by 893 is 0 with a remainder of 459.
The next digit of our result is 0. 
Result so far: 71000.0
The remainder is 459 after subtracting 0 from 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 9:
When dividing 4590 by 893, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 71000.5
Subtract 4465 from 4590 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 10:
If we divide 1250 by 893, we get 1 and a remainder of 357.
The next digit of our result is 1. 
Result so far: 71000.51
Subtracting 893 from 1250 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 11:
The number 893 fits into 3570 3 times, leaving a remainder of 891.
Record the quotient 3 as the next digit in the result. 
Result so far: 71000.513
The remainder is 891 after subtracting 2679 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8910, and continue the process.

Let's proceed to step 12:
8910 divided by 893 is 9 with a remainder of 873.
The number 9 becomes the next digit in our result. 
Result so far: 71000.5139
Subtract 8037 from 8910 to get 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

On to step 13:
8730 divided by 893 is 9 with a remainder of 693.
Put 9 as the next digit of the answer. 
Result so far: 71000.51399
The remainder is 693 after subtracting 8037 from 8730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

The final outcome is 71000.51399, with a leftover of 0.000693.
