Let's divide 66790915 by 987
We want to divide 66790915 by 987.

Let's proceed to step 1:
If we divide 6 by 987, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 987

Step 2:
If we divide 66 by 987, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 987

Going ahead to step 3:
If we divide 667 by 987, we get 0 and a remainder of 667.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 667 after subtracting 0 from 667.
Include the next digit (9) from the dividend after 667, then repeat: 6679 / 987

Advancing to step 4:
If we divide 6679 by 987, we get 6 and a remainder of 757.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5922 from 6679 to get 757.
Append the next digit (0) from the dividend to 757 and continue with: 7570 / 987

Moving on to step 5:
987 goes into 7570 7 times with a remainder of 661.
The next digit of our result is 7. 
Result so far: 67.0
The remainder is 661 after subtracting 6909 from 7570.
Grab the next digit (9) from the dividend, add it to 661, then carry on: 6619 / 987

Advancing to step 6:
When dividing 6619 by 987, we get 6 with a remainder of 697.
Record the quotient 6 as the next digit in the result. 
Result so far: 676.0
Subtracting 5922 from 6619 leaves us with 697.
Append the next digit (1) from the dividend to 697 and continue with: 6971 / 987

Let's proceed to step 7:
When dividing 6971 by 987, we get 7 with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 6767.0
Subtract 6909 from 6971 to get 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 987

Moving on to step 8:
If we divide 625 by 987, we get 0 and a remainder of 625.
Record the quotient 0 as the next digit in the result. 
Result so far: 67670.0
If we subtract 0 from 625, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 9:
The number 987 fits into 6250 6 times, leaving a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 67670.6
Subtract 5922 from 6250 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
3280 divided by 987 is 3 with a remainder of 319.
Use 3 as the next digit of our solution. 
Result so far: 67670.63
If we take 2961 away from 3280, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 11:
987 can be fit into 3190 3 times, resulting in a remainder of 229.
The next digit of our result is 3. 
Result so far: 67670.633
Subtracting 2961 from 3190 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 67670.633, with a leftover of 0.0229.
