We divide 251409 by 70
Let's see how many times 70 fits into 251409.

Step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 70

Let's proceed to step 2:
25 divided by 70 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 70

Step 3:
The number 70 fits into 251 3 times, leaving a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 41 after subtracting 210 from 251.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 70

Advancing to step 4:
If we divide 414 by 70, we get 5 and a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 350 from 414 and we're left with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 70

On to step 5:
640 divided by 70 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 359.0
Subtract 630 from 640 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 70

Moving on to step 6:
70 goes into 109 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 3591.0
Deduct 70 from 109 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 70 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 3591.5
If we subtract 350 from 390, 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.

Going ahead to step 8:
When dividing 400 by 70, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3591.55
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 3591.55, and the remainder is 0.05.
