We look at the division of 78219375 by 801 
Our goal is to divide 78219375 by 801.

Going ahead to step 1:
801 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 801

Step 2:
801 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 801

Let's proceed to step 3:
801 goes into 782 0 times with a remainder of 782.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 782, we get 782.
Append the next digit (1) from the dividend to 782 and continue with: 7821 / 801

Moving on to step 4:
801 goes into 7821 9 times with a remainder of 612.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7209 from 7821 leaves us with 612.
Include the next digit (9) from the dividend after 612, then repeat: 6129 / 801

Going ahead to step 5:
If we divide 6129 by 801, we get 7 and a remainder of 522.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 5607 from 6129 leaves us with 522.
Include the next digit (3) from the dividend after 522, then repeat: 5223 / 801

Advancing to step 6:
801 goes into 5223 6 times with a remainder of 417.
The number 6 becomes the next digit in our result. 
Result so far: 976.0
Deduct 4806 from 5223 and we're left with 417.
Bring next digit (7) of the dividend behind the 417 and repeat the process: 4177 / 801

Let's proceed to step 7:
801 goes into 4177 5 times with a remainder of 172.
Put 5 as the next digit of the answer. 
Result so far: 9765.0
The remainder is 172 after subtracting 4005 from 4177.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 801

Advancing to step 8:
801 can be fit into 1725 2 times, resulting in a remainder of 123.
Put 2 as the next digit of the answer. 
Result so far: 97652.0
Deduct 1602 from 1725 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
1230 divided by 801 is 1 with a remainder of 429.
Put 1 as the next digit of the answer. 
Result so far: 97652.1
Subtract 801 from 1230 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 10:
The number 801 fits into 4290 5 times, leaving a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 97652.15
Deduct 4005 from 4290 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 11:
2850 divided by 801 is 3 with a remainder of 447.
Record the quotient 3 as the next digit in the result. 
Result so far: 97652.153
Subtracting 2403 from 2850 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 12:
If we divide 4470 by 801, we get 5 and a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 97652.1535
Subtracting 4005 from 4470 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 13:
801 goes into 4650 5 times with a remainder of 645.
Use 5 as the next digit of our solution. 
Result so far: 97652.15355
If we subtract 4005 from 4650, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

The final outcome is 97652.15355, with a leftover of 0.000645.
