85990 divided by 89 
Let's see how many times 89 fits into 85990.

Let's proceed to step 1:
8 divided by 89 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 89

Step 2:
When dividing 85 by 89, we get 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 89

Let's proceed to step 3:
The number 89 fits into 859 9 times, leaving a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 801 from 859 to get 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 89

Advancing to step 4:
89 goes into 589 6 times with a remainder of 55.
The next digit of our result is 6. 
Result so far: 96.0
If we take 534 away from 589, we end up with 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 89

Let's proceed to step 5:
550 divided by 89 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 966.0
If we take 534 away from 550, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 6:
The number 89 fits into 160 1 times, leaving a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 966.1
Subtract 89 from 160 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
If we divide 710 by 89, we get 7 and a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 966.17
If we take 623 away from 710, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 8:
89 can be fit into 870 9 times, resulting in a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 966.179
If we take 801 away from 870, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
When dividing 690 by 89, we get 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 966.1797
Deduct 623 from 690 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
If we divide 670 by 89, we get 7 and a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 966.17977
Deduct 623 from 670 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 966.17977, with a leftover of 4.7e-05.
