Let's divide 80278123 by 851
We want to divide 80278123 by 851.

Advancing to step 1:
851 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 851

Going ahead to step 2:
If we divide 80 by 851, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 851

Advancing to step 3:
802 divided by 851 is 0 with a remainder of 802.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 802, we get 802.
Take the next digit (7) from the dividend and append it to 802, then repeat: 8027 / 851

Let's proceed to step 4:
851 goes into 8027 9 times with a remainder of 368.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7659 from 8027, we get 368.
Append the next digit (8) from the dividend to 368 and continue with: 3688 / 851

Moving on to step 5:
When dividing 3688 by 851, we get 4 with a remainder of 284.
The next digit of our result is 4. 
Result so far: 94.0
Subtracting 3404 from 3688 leaves us with 284.
Include the next digit (1) from the dividend after 284, then repeat: 2841 / 851

Moving on to step 6:
2841 divided by 851 is 3 with a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 943.0
If we take 2553 away from 2841, we end up with 288.
Grab the next digit (2) from the dividend, add it to 288, then carry on: 2882 / 851

Advancing to step 7:
851 can be fit into 2882 3 times, resulting in a remainder of 329.
Write down 3 as next digit of the result. 
Result so far: 9433.0
The remainder is 329 after subtracting 2553 from 2882.
Append the next digit (3) from the dividend to 329 and continue with: 3293 / 851

Step 8:
When dividing 3293 by 851, we get 3 with a remainder of 740.
Write down 3 as next digit of the result. 
Result so far: 94333.0
The remainder is 740 after subtracting 2553 from 3293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 9:
The number 851 fits into 7400 8 times, leaving a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 94333.8
Subtract 6808 from 7400 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 10:
851 goes into 5920 6 times with a remainder of 814.
Use 6 as the next digit of our solution. 
Result so far: 94333.86
Deduct 5106 from 5920 and we're left with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Step 11:
The number 851 fits into 8140 9 times, leaving a remainder of 481.
The next digit of our result is 9. 
Result so far: 94333.869
The remainder is 481 after subtracting 7659 from 8140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 12:
851 can be fit into 4810 5 times, resulting in a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 94333.8695
Deduct 4255 from 4810 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

On to step 13:
The number 851 fits into 5550 6 times, leaving a remainder of 444.
Use 6 as the next digit of our solution. 
Result so far: 94333.86956
If we subtract 5106 from 5550, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 14:
4440 divided by 851 is 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 94333.869565
If we subtract 4255 from 4440, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 15:
1850 divided by 851 is 2 with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 94333.8695652
If we take 1702 away from 1850, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 16:
1480 divided by 851 is 1 with a remainder of 629.
Write down 1 as next digit of the result. 
Result so far: 94333.86956521
If we take 851 away from 1480, we end up with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

After the division, we end up with 94333.86956521 and a remainder of 6.29e-07.
