310243 ÷ 70 
We're looking to find how many times 70 goes into 310243.

On to step 1:
When dividing 3 by 70, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 70

On to step 2:
31 divided by 70 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 70

Going ahead to step 3:
When dividing 310 by 70, we get 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 280 from 310 leaves us with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 70

Moving on to step 4:
When dividing 302 by 70, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 280 away from 302, we end up with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 70

Let's proceed to step 5:
224 divided by 70 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
The remainder is 14 after subtracting 210 from 224.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 70

Going ahead to step 6:
143 divided by 70 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 4432.0
Subtract 140 from 143 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 70, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4432.0
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.

Step 8:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4432.04
The remainder is 20 after subtracting 280 from 300.
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 9:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4432.042
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.

Moving on to step 10:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 4432.0428
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.

Let's proceed to step 11:
400 divided by 70 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4432.04285
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.

Step 12:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 4432.042857
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.

Advancing to step 13:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 4432.0428571
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.

Let's proceed to step 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4432.04285714
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.

After the division, we end up with 4432.04285714 and a remainder of 2e-08.
