258520 ÷ 70 
We want to divide 258520 by 70.

On to step 1:
When dividing 2 by 70, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 70

On to step 2:
When dividing 25 by 70, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 70

On to step 3:
70 can be fit into 258 3 times, resulting in a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 210 from 258 leaves us with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 70

On to step 4:
70 goes into 485 6 times with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 420 from 485 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 70

On to step 5:
70 goes into 652 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 369.0
If we subtract 630 from 652, we get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 70

Step 6:
70 goes into 220 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3693.0
If we take 210 away from 220, 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.

Let's proceed to step 7:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 3693.1
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 8:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3693.14
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.

Let's proceed to step 9:
If we divide 200 by 70, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 3693.142
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.

Going ahead to step 10:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 3693.1428
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.

Let's proceed to step 11:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3693.14285
The remainder is 50 after subtracting 350 from 400.
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:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 3693.142857
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.

Let's proceed to step 13:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 3693.1428571
If we take 70 away from 100, 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.

On to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3693.14285714
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.

Our division results in 3693.14285714 with a remaining 2e-08.
