Let's divide 645339 by 89
We want to divide 645339 by 89.

Let's proceed to step 1:
6 divided by 89 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 89

Going ahead to step 2:
The number 89 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 89

Going ahead to step 3:
When dividing 645 by 89, we get 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 623 from 645 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 89

Advancing to step 4:
89 can be fit into 223 2 times, resulting in a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 178 from 223 leaves us with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 89

Moving on to step 5:
89 goes into 453 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 725.0
If we subtract 445 from 453, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 89

Going ahead to step 6:
If we divide 89 by 89, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 7251.0
If we take 89 away from 89, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
89 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7251.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
89 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7251.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7251.0, and the remainder is 0.0.
