858444 ÷ 89 
Our goal is to divide 858444 by 89.

Step 1:
When dividing 8 by 89, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 89

Let's proceed to step 2:
85 divided by 89 is 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 89

Let's proceed to step 3:
89 can be fit into 858 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 801 from 858, we get 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 89

On to step 4:
89 goes into 574 6 times with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 40 after subtracting 534 from 574.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 89

Advancing to step 5:
89 goes into 404 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 964.0
Subtract 356 from 404 to get 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 89

Moving on to step 6:
The number 89 fits into 484 5 times, leaving a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 9645.0
Subtract 445 from 484 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
If we divide 390 by 89, we get 4 and a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 9645.4
Subtracting 356 from 390 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
89 can be fit into 340 3 times, resulting in a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 9645.43
If we take 267 away from 340, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
When dividing 730 by 89, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 9645.438
If we take 712 away from 730, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
If we divide 180 by 89, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 9645.4382
Subtracting 178 from 180 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 89, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9645.4382
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
89 can be fit into 200 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 9645.438202
If we subtract 178 from 200, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
When dividing 220 by 89, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 9645.4382022
Subtract 178 from 220 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 9645.4382022 with a remainder of 4.2e-07.
