72859891 ÷ 803 
Let's see how many times 803 fits into 72859891.

On to step 1:
When dividing 7 by 803, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 803

Moving on to step 2:
72 divided by 803 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 803

Moving on to step 3:
The number 803 fits into 728 0 times, leaving a remainder of 728.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 728, we end up with 728.
Include the next digit (5) from the dividend after 728, then repeat: 7285 / 803

Step 4:
When dividing 7285 by 803, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 58 after subtracting 7227 from 7285.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 803

Advancing to step 5:
589 divided by 803 is 0 with a remainder of 589.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 589 and we're left with 589.
Append the next digit (8) from the dividend to 589 and continue with: 5898 / 803

Going ahead to step 6:
803 goes into 5898 7 times with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 907.0
If we subtract 5621 from 5898, we get 277.
Grab the next digit (9) from the dividend, add it to 277, then carry on: 2779 / 803

Step 7:
803 can be fit into 2779 3 times, resulting in a remainder of 370.
The next digit of our result is 3. 
Result so far: 9073.0
Subtract 2409 from 2779 to get 370.
Grab the next digit (1) from the dividend, add it to 370, then carry on: 3701 / 803

On to step 8:
When dividing 3701 by 803, we get 4 with a remainder of 489.
Write down 4 as next digit of the result. 
Result so far: 90734.0
If we subtract 3212 from 3701, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
When dividing 4890 by 803, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 90734.6
Subtracting 4818 from 4890 leaves us 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.

Advancing to step 10:
803 goes into 720 0 times with a remainder of 720.
The next digit of our result is 0. 
Result so far: 90734.6
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 11:
7200 divided by 803 is 8 with a remainder of 776.
Record the quotient 8 as the next digit in the result. 
Result so far: 90734.608
Subtract 6424 from 7200 to get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Going ahead to step 12:
When dividing 7760 by 803, we get 9 with a remainder of 533.
Record the quotient 9 as the next digit in the result. 
Result so far: 90734.6089
Deduct 7227 from 7760 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Advancing to step 13:
5330 divided by 803 is 6 with a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 90734.60896
Subtracting 4818 from 5330 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 14:
803 can be fit into 5120 6 times, resulting in a remainder of 302.
The number 6 becomes the next digit in our result. 
Result so far: 90734.608966
If we subtract 4818 from 5120, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

After the division, we end up with 90734.608966 and a remainder of 3.02e-05.
