319990 ÷ 70 
We want to divide 319990 by 70.

On to step 1:
3 divided by 70 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 70

Going ahead to step 2:
70 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 70

Advancing to step 3:
70 goes into 319 4 times with a remainder of 39.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 280 from 319 and we're left with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 70

Moving on to step 4:
When dividing 399 by 70, we get 5 with a remainder of 49.
The next digit of our result is 5. 
Result so far: 45.0
If we take 350 away from 399, we end up with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 70

Step 5:
499 divided by 70 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 457.0
Subtracting 490 from 499 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 70

Let's proceed to step 6:
70 goes into 90 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 4571.0
If we take 70 away from 90, 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.

Advancing to step 7:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 4571.2
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.

Moving on to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 4571.28
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.

Going ahead to step 9:
70 goes into 400 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4571.285
Deduct 350 from 400 and we're left 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.

Moving on to step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 4571.2857
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.

Step 11:
100 divided by 70 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 4571.28571
Subtracting 70 from 100 leaves us 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.

Advancing to step 12:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4571.285714
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.

Moving on to step 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 4571.2857142
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 14:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4571.28571428
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.

Our division results in 4571.28571428 with a remaining 4e-08.
