Let's divide 23258987 by 70
We're looking to find how many times 70 goes into 23258987.

Advancing to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 70

On to step 2:
70 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 70

Going ahead to step 3:
70 goes into 232 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 210 from 232, we get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 70

On to step 4:
If we divide 225 by 70, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 210 from 225, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 70

On to step 5:
The number 70 fits into 158 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 332.0
Subtract 140 from 158 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 70

Moving on to step 6:
189 divided by 70 is 2 with a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 3322.0
If we take 140 away from 189, we end up with 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 70

Step 7:
If we divide 498 by 70, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 33227.0
Subtracting 490 from 498 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 70

On to step 8:
87 divided by 70 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 332271.0
The remainder is 17 after subtracting 70 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
The number 70 fits into 170 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 332271.2
If we take 140 away from 170, 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.

Step 10:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 332271.24
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.

On to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 332271.242
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.

Moving on to step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 332271.2428
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.

Moving on to step 13:
400 divided by 70 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 332271.24285
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.

Let's proceed to step 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 332271.242857
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.

On to step 15:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 332271.2428571
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.

Moving on to step 16:
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: 332271.24285714
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.

The quotient of the division is 332271.24285714, and the remainder is 2e-08.
