Let's divide 900851 by 89
We're looking to find how many times 89 goes into 900851.

Advancing to step 1:
If we divide 9 by 89, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 89

Advancing to step 2:
90 divided by 89 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 89 from 90 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 89

Going ahead to step 3:
The number 89 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 89

Let's proceed to step 4:
108 divided by 89 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 89 from 108 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 89

Going ahead to step 5:
89 can be fit into 195 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 1012.0
Subtract 178 from 195 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 89

Step 6:
89 can be fit into 171 1 times, resulting in a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 10121.0
Subtracting 89 from 171 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 7:
89 can be fit into 820 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 10121.9
Subtracting 801 from 820 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
190 divided by 89 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 10121.92
The remainder is 12 after subtracting 178 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 89, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 10121.921
If we take 89 away from 120, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
310 divided by 89 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 10121.9213
If we take 267 away from 310, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
89 can be fit into 430 4 times, resulting in a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 10121.92134
Subtract 356 from 430 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
89 can be fit into 740 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 10121.921348
Subtracting 712 from 740 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
The number 89 fits into 280 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 10121.9213483
Subtract 267 from 280 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
89 can be fit into 130 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 10121.92134831
Deduct 89 from 130 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 10121.92134831 and a remainder of 4.1e-08.
