Let's divide 66123088 by 890
We want to figure out the number of times 66123088 can be divided by 890.

Step 1:
890 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 890

Step 2:
If we divide 66 by 890, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 890

Let's proceed to step 3:
When dividing 661 by 890, we get 0 with a remainder of 661.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 661, we end up with 661.
Include the next digit (2) from the dividend after 661, then repeat: 6612 / 890

Advancing to step 4:
If we divide 6612 by 890, we get 7 and a remainder of 382.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 6230 from 6612, we get 382.
Grab the next digit (3) from the dividend, add it to 382, then carry on: 3823 / 890

Advancing to step 5:
3823 divided by 890 is 4 with a remainder of 263.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 3560 from 3823 to get 263.
Take the next digit (0) from the dividend and append it to 263, then repeat: 2630 / 890

Advancing to step 6:
When dividing 2630 by 890, we get 2 with a remainder of 850.
The next digit of our result is 2. 
Result so far: 742.0
Subtract 1780 from 2630 to get 850.
Bring next digit (8) of the dividend behind the 850 and repeat the process: 8508 / 890

On to step 7:
When dividing 8508 by 890, we get 9 with a remainder of 498.
The next digit of our result is 9. 
Result so far: 7429.0
Subtract 8010 from 8508 to get 498.
Append the next digit (8) from the dividend to 498 and continue with: 4988 / 890

Moving on to step 8:
890 can be fit into 4988 5 times, resulting in a remainder of 538.
The next digit of our result is 5. 
Result so far: 74295.0
Deduct 4450 from 4988 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 9:
When dividing 5380 by 890, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 74295.6
Subtracting 5340 from 5380 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 890 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 74295.6
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
If we divide 4000 by 890, we get 4 and a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 74295.604
If we take 3560 away from 4000, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
When dividing 4400 by 890, we get 4 with a remainder of 840.
Write down 4 as next digit of the result. 
Result so far: 74295.6044
Deduct 3560 from 4400 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

The final outcome is 74295.6044, with a leftover of 0.0084.
