We look at the division of 646424 by 89 
We want to divide 646424 by 89.

Going ahead to step 1:
6 divided by 89 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 89

Step 2:
When dividing 64 by 89, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 89

Step 3:
When dividing 646 by 89, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 623 from 646 leaves us with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 89

On to step 4:
89 goes into 234 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtracting 178 from 234 leaves us with 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 89

Going ahead to step 5:
89 can be fit into 562 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 726.0
Subtracting 534 from 562 leaves us with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 89

Moving on to step 6:
When dividing 284 by 89, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 7263.0
The remainder is 17 after subtracting 267 from 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 89 fits into 170 1 times, leaving a remainder of 81.
The next digit of our result is 1. 
Result so far: 7263.1
If we take 89 away from 170, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 8:
The number 89 fits into 810 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 7263.19
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.

On to step 9:
90 divided by 89 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 7263.191
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.

Step 10:
10 divided by 89 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7263.191
Subtract 0 from 10 to get 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 11:
100 divided by 89 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 7263.19101
The remainder is 11 after subtracting 89 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
110 divided by 89 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 7263.191011
Subtract 89 from 110 to get 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 7263.191011 and a remainder of 2.1e-06.
