We look at the division of 63680385 by 70 
We want to divide 63680385 by 70.

Advancing to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 70

Advancing to step 2:
If we divide 63 by 70, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 70

Moving on to step 3:
636 divided by 70 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 6 after subtracting 630 from 636.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 70

Step 4:
70 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 70

Going ahead to step 5:
70 can be fit into 680 9 times, resulting in a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 909.0
The remainder is 50 after subtracting 630 from 680.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 70

Let's proceed to step 6:
The number 70 fits into 503 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 9097.0
If we subtract 490 from 503, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 70

On to step 7:
138 divided by 70 is 1 with a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 90971.0
If we subtract 70 from 138, we get 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 70

Moving on to step 8:
When dividing 685 by 70, we get 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 909719.0
If we take 630 away from 685, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
70 goes into 550 7 times with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 909719.7
Subtracting 490 from 550 leaves us 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.

Step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 909719.78
If we take 560 away from 600, 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.

Moving on to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 909719.785
Subtract 350 from 400 to 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 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 909719.7857
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 909719.78571
If we subtract 70 from 100, we get 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 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 909719.785714
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 909719.7857142
Subtracting 140 from 200 leaves us 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.

Let's proceed to step 16:
If we divide 600 by 70, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 909719.78571428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 909719.78571428 with a remaining 4e-08.
