Let's divide 804640 by 70
We want to figure out the number of times 804640 can be divided by 70.

Advancing to step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 70

Step 2:
When dividing 80 by 70, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 70 from 80 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 70

On to step 3:
If we divide 104 by 70, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 34 after subtracting 70 from 104.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 70

Advancing to step 4:
The number 70 fits into 346 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Deduct 280 from 346 and we're left with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 70

On to step 5:
70 goes into 664 9 times with a remainder of 34.
The next digit of our result is 9. 
Result so far: 1149.0
Subtracting 630 from 664 leaves us with 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 70

Let's proceed to step 6:
70 can be fit into 340 4 times, resulting in a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 11494.0
If we take 280 away from 340, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 11494.8
If we subtract 560 from 600, we 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.

Going ahead to step 8:
70 goes into 400 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11494.85
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 11494.857
If we take 490 away from 500, we end up 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.

Moving on to step 10:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 11494.8571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 11494.85714
Subtracting 280 from 300 leaves us 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.

Let's proceed to step 12:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11494.857142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 11494.8571428
Subtract 560 from 600 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.

Advancing to step 14:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11494.85714285
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 11494.85714285 with a balance of 5e-08.
