We're dividing 66602805 by 989 
We want to divide 66602805 by 989.

Going ahead to step 1:
The number 989 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 989

On to step 2:
The number 989 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 989

On to step 3:
989 can be fit into 666 0 times, resulting in a remainder of 666.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 666, we end up with 666.
Take the next digit (0) from the dividend and append it to 666, then repeat: 6660 / 989

Going ahead to step 4:
If we divide 6660 by 989, we get 6 and a remainder of 726.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 5934 from 6660, we get 726.
Fetch the next digit (2) from the dividend, attach it to 726 and continue: 7262 / 989

Advancing to step 5:
When dividing 7262 by 989, we get 7 with a remainder of 339.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 6923 from 7262 leaves us with 339.
Grab the next digit (8) from the dividend, add it to 339, then carry on: 3398 / 989

Advancing to step 6:
The number 989 fits into 3398 3 times, leaving a remainder of 431.
The number 3 becomes the next digit in our result. 
Result so far: 673.0
If we subtract 2967 from 3398, we get 431.
Bring next digit (0) of the dividend behind the 431 and repeat the process: 4310 / 989

Going ahead to step 7:
4310 divided by 989 is 4 with a remainder of 354.
Write down 4 as next digit of the result. 
Result so far: 6734.0
The remainder is 354 after subtracting 3956 from 4310.
Include the next digit (5) from the dividend after 354, then repeat: 3545 / 989

Advancing to step 8:
3545 divided by 989 is 3 with a remainder of 578.
Put 3 as the next digit of the answer. 
Result so far: 67343.0
If we take 2967 away from 3545, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 9:
989 can be fit into 5780 5 times, resulting in a remainder of 835.
The number 5 becomes the next digit in our result. 
Result so far: 67343.5
If we subtract 4945 from 5780, we get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Moving on to step 10:
When dividing 8350 by 989, we get 8 with a remainder of 438.
The number 8 becomes the next digit in our result. 
Result so far: 67343.58
Subtract 7912 from 8350 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 11:
989 goes into 4380 4 times with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 67343.584
Subtracting 3956 from 4380 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 12:
989 can be fit into 4240 4 times, resulting in a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 67343.5844
The remainder is 284 after subtracting 3956 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

After the division, we end up with 67343.5844 and a remainder of 0.00284.
