663743 ÷ 70 
Let's see how many times 70 fits into 663743.

Let's proceed to step 1:
6 divided by 70 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 70

Let's proceed to step 2:
When dividing 66 by 70, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 70

Step 3:
The number 70 fits into 663 9 times, leaving a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 630 away from 663, we end up with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 70

On to step 4:
70 can be fit into 337 4 times, resulting in a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we take 280 away from 337, we end up with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 70

Going ahead to step 5:
574 divided by 70 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 948.0
The remainder is 14 after subtracting 560 from 574.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 70

Advancing to step 6:
When dividing 143 by 70, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 9482.0
Deduct 140 from 143 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 70, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9482.0
If we take 0 away from 30, we end up 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 8:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 9482.04
Subtract 280 from 300 to 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 9:
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: 9482.042
If we subtract 140 from 200, we get 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 10:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 9482.0428
Subtracting 560 from 600 leaves us 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.

Advancing to step 11:
70 goes into 400 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 9482.04285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 9482.042857
Subtracting 490 from 500 leaves us 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.

Going ahead to step 13:
100 divided by 70 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 9482.0428571
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.

Moving on to step 14:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9482.04285714
If we take 280 away from 300, we end up 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.

The final outcome is 9482.04285714, with a leftover of 2e-08.
