802603 ÷ 78 
We want to divide 802603 by 78.

On to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 78

Let's proceed to step 2:
80 divided by 78 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 78 from 80 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 78

Advancing to step 3:
78 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 78

Advancing to step 4:
The number 78 fits into 226 2 times, leaving a remainder of 70.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 156 from 226 leaves us with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 78

Step 5:
If we divide 700 by 78, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 1028.0
If we subtract 624 from 700, we get 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 78

Going ahead to step 6:
763 divided by 78 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 10289.0
Subtracting 702 from 763 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
610 divided by 78 is 7 with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 10289.7
Deduct 546 from 610 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10289.78
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 78, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10289.782
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 78, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10289.782
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 78 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10289.78205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 78 fits into 100 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 10289.782051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 10289.7820512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
When dividing 640 by 78, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 10289.78205128
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 10289.78205128 and a remainder of 1.6e-08.
