We look at the division of 70305746 by 80 
We're looking to find how many times 80 goes into 70305746.

Step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 80

Going ahead to step 2:
If we divide 70 by 80, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 80

Advancing to step 3:
80 can be fit into 703 8 times, resulting in a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 640 from 703 and we're left with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 80

Going ahead to step 4:
80 goes into 630 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 560 from 630 to get 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 80

Let's proceed to step 5:
80 can be fit into 705 8 times, resulting in a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
Subtracting 640 from 705 leaves us with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 80

On to step 6:
The number 80 fits into 657 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 8788.0
If we take 640 away from 657, we end up with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 80

Moving on to step 7:
When dividing 174 by 80, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 87882.0
The remainder is 14 after subtracting 160 from 174.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 80

Advancing to step 8:
80 goes into 146 1 times with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 878821.0
If we take 80 away from 146, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
660 divided by 80 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 878821.8
Deduct 640 from 660 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 878821.82
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 878821.825
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 878821.825
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 878821.825
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 878821.825 with a remaining 0.0.
