670849 ÷ 70 
We're looking to find how many times 70 goes into 670849.

Moving on to step 1:
70 can be fit into 6 0 times, resulting in 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.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 70

Going ahead to step 2:
70 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 70

Let's proceed to step 3:
70 goes into 670 9 times with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 630 from 670 leaves us with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 70

Let's proceed to step 4:
408 divided by 70 is 5 with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtract 350 from 408 to get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 70

Step 5:
584 divided by 70 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 958.0
The remainder is 24 after subtracting 560 from 584.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 70

On to step 6:
70 goes into 249 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 9583.0
If we take 210 away from 249, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
When dividing 390 by 70, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 9583.5
Subtract 350 from 390 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 8:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9583.55
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.

The quotient of the division is 9583.55, and the remainder is 0.05.
