We're dividing 843712 by 89 
We want to figure out the number of times 843712 can be divided by 89.

Step 1:
If we divide 8 by 89, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 89

Let's proceed to step 2:
When dividing 84 by 89, we get 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (3) from the dividend, attach it to 84 and continue: 843 / 89

Moving on to step 3:
If we divide 843 by 89, we get 9 and a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 801 from 843 to get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 89

Let's proceed to step 4:
89 goes into 427 4 times with a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
The remainder is 71 after subtracting 356 from 427.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 89

Going ahead to step 5:
When dividing 711 by 89, we get 7 with a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 947.0
If we subtract 623 from 711, we get 88.
Fetch the next digit (2) from the dividend, attach it to 88 and continue: 882 / 89

Going ahead to step 6:
882 divided by 89 is 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 9479.0
Subtract 801 from 882 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
If we divide 810 by 89, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9479.9
Deduct 801 from 810 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
The number 89 fits into 90 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 9479.91
If we subtract 89 from 90, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
10 divided by 89 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9479.91
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.

Step 10:
100 divided by 89 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 9479.9101
Deduct 89 from 100 and we're left 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.

On to step 11:
When dividing 110 by 89, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 9479.91011
Subtracting 89 from 110 leaves us 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.

After the division, we end up with 9479.91011 and a remainder of 2.1e-05.
