15400 divided by 70 
Our goal is to divide 15400 by 70.

Moving on to step 1:
When dividing 1 by 70, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 70

Moving on to step 2:
The number 70 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 70

Let's proceed to step 3:
154 divided by 70 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 140 from 154 and we're left with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 70

Let's proceed to step 4:
If we divide 140 by 70, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 0 after subtracting 140 from 140.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 70

Let's proceed to step 5:
When dividing 0 by 70, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 220.0
Deduct 0 from 0 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.

Step 6:
If we divide 0 by 70, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 220.0
If we take 0 away from 0, we end up 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.

Step 7:
If we divide 0 by 70, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 220.0
Deduct 0 from 0 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.

Our division results in 220.0 with a remaining 0.0.
