We're dividing 70889697 by 489 
We want to divide 70889697 by 489.

Let's proceed to step 1:
When dividing 7 by 489, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 489

Advancing to step 2:
If we divide 70 by 489, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 489

Step 3:
When dividing 708 by 489, we get 1 with a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 489 away from 708, we end up with 219.
Fetch the next digit (8) from the dividend, attach it to 219 and continue: 2198 / 489

On to step 4:
When dividing 2198 by 489, we get 4 with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1956 from 2198 and we're left with 242.
Include the next digit (9) from the dividend after 242, then repeat: 2429 / 489

Advancing to step 5:
489 can be fit into 2429 4 times, resulting in a remainder of 473.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 1956 from 2429, we get 473.
Bring next digit (6) of the dividend behind the 473 and repeat the process: 4736 / 489

Moving on to step 6:
The number 489 fits into 4736 9 times, leaving a remainder of 335.
Record the quotient 9 as the next digit in the result. 
Result so far: 1449.0
Subtracting 4401 from 4736 leaves us with 335.
Append the next digit (9) from the dividend to 335 and continue with: 3359 / 489

Let's proceed to step 7:
489 goes into 3359 6 times with a remainder of 425.
Use 6 as the next digit of our solution. 
Result so far: 14496.0
The remainder is 425 after subtracting 2934 from 3359.
Append the next digit (7) from the dividend to 425 and continue with: 4257 / 489

Moving on to step 8:
If we divide 4257 by 489, we get 8 and a remainder of 345.
Record the quotient 8 as the next digit in the result. 
Result so far: 144968.0
Subtracting 3912 from 4257 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 9:
When dividing 3450 by 489, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 144968.7
Deduct 3423 from 3450 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
The number 489 fits into 270 0 times, leaving a remainder of 270.
The next digit of our result is 0. 
Result so far: 144968.7
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
The number 489 fits into 2700 5 times, leaving a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 144968.705
Subtracting 2445 from 2700 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 12:
If we divide 2550 by 489, we get 5 and a remainder of 105.
The next digit of our result is 5. 
Result so far: 144968.7055
Subtract 2445 from 2550 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 144968.7055 with a remainder of 0.00105.
