We're dividing 312419 by 70 
Let's see how many times 70 fits into 312419.

Going ahead to step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 70

Going ahead to step 2:
The number 70 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 70

Moving on to step 3:
If we divide 312 by 70, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 280 from 312 and we're left with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 70

Moving on to step 4:
70 can be fit into 324 4 times, resulting in a remainder of 44.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 280 from 324 and we're left with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 70

Step 5:
The number 70 fits into 441 6 times, leaving a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 446.0
If we subtract 420 from 441, we get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 70

On to step 6:
The number 70 fits into 219 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 4463.0
Subtracting 210 from 219 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 70, we get 1 and a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 4463.1
Subtract 70 from 90 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.

Let's proceed to step 8:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 4463.12
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.

Advancing to step 9:
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: 4463.128
If we subtract 560 from 600, we 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.

Going ahead to step 10:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4463.1285
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 11:
500 divided by 70 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 4463.12857
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.

Going ahead to step 12:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 4463.128571
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.

Moving on to step 13:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4463.1285714
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.

Advancing to step 14:
If we divide 200 by 70, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 4463.12857142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 4463.12857142, with a leftover of 6e-08.
