We look at the division of 345690 by 70 
We want to divide 345690 by 70.

On 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
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 70

Going ahead to step 2:
The number 70 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 70

On to step 3:
70 goes into 345 4 times with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 65 after subtracting 280 from 345.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 70

Moving on to step 4:
When dividing 656 by 70, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 630 from 656, we get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 70

Going ahead to step 5:
70 goes into 269 3 times with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 493.0
Deduct 210 from 269 and we're left with 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 70

On to step 6:
The number 70 fits into 590 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 4938.0
Deduct 560 from 590 and we're left 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.

Going ahead to step 7:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4938.4
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.

On to step 8:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 4938.42
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.

Step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4938.428
Deduct 560 from 600 and we're left 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 10:
70 goes into 400 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4938.4285
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.

Step 11:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 4938.42857
Subtract 490 from 500 to 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.

On to step 12:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 4938.428571
Deduct 70 from 100 and we're left 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:
If we divide 300 by 70, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 4938.4285714
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.

Advancing to step 14:
When dividing 200 by 70, we get 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 4938.42857142
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.

After the division, we end up with 4938.42857142 and a remainder of 6e-08.
