66988385 ÷ 989 
We want to divide 66988385 by 989.

Let's proceed to step 1:
The number 989 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 989

Let's proceed to step 2:
989 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 989

Let's proceed to step 3:
If we divide 669 by 989, we get 0 and a remainder of 669.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 669 after subtracting 0 from 669.
Bring next digit (8) of the dividend behind the 669 and repeat the process: 6698 / 989

Going ahead to step 4:
989 can be fit into 6698 6 times, resulting in a remainder of 764.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 5934 from 6698 to get 764.
Fetch the next digit (8) from the dividend, attach it to 764 and continue: 7648 / 989

Moving on to step 5:
7648 divided by 989 is 7 with a remainder of 725.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtracting 6923 from 7648 leaves us with 725.
Take the next digit (3) from the dividend and append it to 725, then repeat: 7253 / 989

Advancing to step 6:
989 goes into 7253 7 times with a remainder of 330.
Record the quotient 7 as the next digit in the result. 
Result so far: 677.0
Subtracting 6923 from 7253 leaves us with 330.
Append the next digit (8) from the dividend to 330 and continue with: 3308 / 989

Moving on to step 7:
989 goes into 3308 3 times with a remainder of 341.
Record the quotient 3 as the next digit in the result. 
Result so far: 6773.0
Deduct 2967 from 3308 and we're left with 341.
Include the next digit (5) from the dividend after 341, then repeat: 3415 / 989

Let's proceed to step 8:
When dividing 3415 by 989, we get 3 with a remainder of 448.
Write down 3 as next digit of the result. 
Result so far: 67733.0
If we take 2967 away from 3415, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 9:
989 can be fit into 4480 4 times, resulting in a remainder of 524.
The next digit of our result is 4. 
Result so far: 67733.4
Deduct 3956 from 4480 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 10:
The number 989 fits into 5240 5 times, leaving a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 67733.45
Deduct 4945 from 5240 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 11:
989 goes into 2950 2 times with a remainder of 972.
Put 2 as the next digit of the answer. 
Result so far: 67733.452
The remainder is 972 after subtracting 1978 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9720, and continue the process.

Let's proceed to step 12:
When dividing 9720 by 989, we get 9 with a remainder of 819.
The number 9 becomes the next digit in our result. 
Result so far: 67733.4529
Subtracting 8901 from 9720 leaves us with 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Going ahead to step 13:
If we divide 8190 by 989, we get 8 and a remainder of 278.
Put 8 as the next digit of the answer. 
Result so far: 67733.45298
If we subtract 7912 from 8190, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 14:
2780 divided by 989 is 2 with a remainder of 802.
Write down 2 as next digit of the result. 
Result so far: 67733.452982
Subtract 1978 from 2780 to get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Advancing to step 15:
When dividing 8020 by 989, we get 8 with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 67733.4529828
If we take 7912 away from 8020, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 16:
When dividing 1080 by 989, we get 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 67733.45298281
If we subtract 989 from 1080, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final result is 67733.45298281 with a remainder of 9.1e-08.
