100512 ÷ 70 
Let's see how many times 70 fits into 100512.

Let's proceed to step 1:
1 divided by 70 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 70

Let's proceed to step 2:
The number 70 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 70

Moving on to step 3:
100 divided by 70 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 70 away from 100, we end up with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 70

Moving on to step 4:
The number 70 fits into 305 4 times, leaving a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 280 from 305, we get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 70

Step 5:
251 divided by 70 is 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtract 210 from 251 to get 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 70

Advancing to step 6:
When dividing 412 by 70, we get 5 with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 1435.0
If we subtract 350 from 412, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
If we divide 620 by 70, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 1435.8
If we subtract 560 from 620, we 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.

Moving on to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 1435.88
Subtract 560 from 600 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.

The quotient of the division is 1435.88, and the remainder is 0.04.
