Let's divide 23870288 by 70
Our goal is to divide 23870288 by 70.

Moving on to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 70

On to step 2:
70 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 70

Moving on to step 3:
The number 70 fits into 238 3 times, leaving a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 28 after subtracting 210 from 238.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 70

Advancing to step 4:
70 can be fit into 287 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 280 from 287, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 70

On to step 5:
70 divided by 70 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 341.0
Subtracting 70 from 70 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 70

Let's proceed to step 6:
70 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 3410.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 70

Step 7:
70 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 34100.0
If we subtract 0 from 28, we get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 70

Advancing to step 8:
70 goes into 288 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 341004.0
Deduct 280 from 288 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 70, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 341004.1
The remainder is 10 after subtracting 70 from 80.
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:
70 goes into 100 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 341004.11
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 341004.11, and the remainder is 0.03.
