We look at the division of 307122 by 70 
Our goal is to divide 307122 by 70.

Going ahead to step 1:
If we divide 3 by 70, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 70

On to step 2:
70 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 70

Advancing to step 3:
70 can be fit into 307 4 times, resulting in a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 280 from 307 and we're left with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 70

On to step 4:
If we divide 271 by 70, we get 3 and a remainder of 61.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 210 from 271, we get 61.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 70

On to step 5:
612 divided by 70 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 438.0
The remainder is 52 after subtracting 560 from 612.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 70

Going ahead to step 6:
70 goes into 522 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 4387.0
The remainder is 32 after subtracting 490 from 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
The number 70 fits into 320 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 4387.4
Subtract 280 from 320 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:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4387.45
Subtracting 350 from 400 leaves us 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.

Going ahead to step 9:
When dividing 500 by 70, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 4387.457
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 10:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 4387.4571
Subtract 70 from 100 to 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.

On to step 11:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4387.45714
If we subtract 280 from 300, we 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 12:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4387.457142
Subtract 140 from 200 to 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.

Step 13:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 4387.4571428
If we take 560 away from 600, we end up 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.

Moving on to step 14:
400 divided by 70 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4387.45714285
Subtracting 350 from 400 leaves us 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.

The final result is 4387.45714285 with a remainder of 5e-08.
