Let's divide 123970 by 8
We want to figure out the number of times 123970 can be divided by 8.

Going ahead to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 8

On to step 2:
12 divided by 8 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 8 from 12.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 8

Going ahead to step 3:
8 goes into 43 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 40 from 43 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 8

Let's proceed to step 4:
If we divide 39 by 8, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
The remainder is 7 after subtracting 32 from 39.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 8

Going ahead to step 5:
77 divided by 8 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1549.0
The remainder is 5 after subtracting 72 from 77.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

Moving on to step 6:
50 divided by 8 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 15496.0
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 15496.2
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15496.25
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15496.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15496.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15496.25, and the remainder is 0.0.
