987820 divided by 89 
We're looking to find how many times 89 goes into 987820.

Moving on to step 1:
9 divided by 89 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 89

On to step 2:
If we divide 98 by 89, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 89 from 98 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 89

Let's proceed to step 3:
89 goes into 97 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 8 after subtracting 89 from 97.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 89

Going ahead to step 4:
89 can be fit into 88 0 times, resulting in a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Deduct 0 from 88 and we're left with 88.
Append the next digit (2) from the dividend to 88 and continue with: 882 / 89

Moving on to step 5:
89 goes into 882 9 times with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 1109.0
The remainder is 81 after subtracting 801 from 882.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 89

Advancing to step 6:
810 divided by 89 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 11099.0
Subtract 801 from 810 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 89, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11099.1
The remainder is 1 after subtracting 89 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 89 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11099.1
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
89 goes into 100 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11099.101
Subtracting 89 from 100 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
89 goes into 110 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 11099.1011
Deduct 89 from 110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 11099.1011, with a leftover of 0.00021.
