45126 divided by 89 
We want to figure out the number of times 45126 can be divided by 89.

Advancing to step 1:
4 divided by 89 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 89

Advancing to step 2:
When dividing 45 by 89, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 89

Step 3:
When dividing 451 by 89, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 6 after subtracting 445 from 451.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 89

Advancing to step 4:
The number 89 fits into 62 0 times, leaving a remainder of 62.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 62 after subtracting 0 from 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 89

Advancing to step 5:
626 divided by 89 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 507.0
If we subtract 623 from 626, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
89 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 507.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
89 goes into 300 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 507.03
Deduct 267 from 300 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
89 goes into 330 3 times with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 507.033
If we take 267 away from 330, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 507.033, with a leftover of 0.0063.
