We're dividing 89088646 by 538 
We want to figure out the number of times 89088646 can be divided by 538.

On to step 1:
538 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 538

Advancing to step 2:
89 divided by 538 is 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Append the next digit (0) from the dividend to 89 and continue with: 890 / 538

On to step 3:
When dividing 890 by 538, we get 1 with a remainder of 352.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 538 from 890 to get 352.
Fetch the next digit (8) from the dividend, attach it to 352 and continue: 3528 / 538

Advancing to step 4:
538 goes into 3528 6 times with a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3228 from 3528, we get 300.
Take the next digit (8) from the dividend and append it to 300, then repeat: 3008 / 538

Let's proceed to step 5:
538 goes into 3008 5 times with a remainder of 318.
The next digit of our result is 5. 
Result so far: 165.0
Subtracting 2690 from 3008 leaves us with 318.
Bring next digit (6) of the dividend behind the 318 and repeat the process: 3186 / 538

On to step 6:
538 can be fit into 3186 5 times, resulting in a remainder of 496.
Write down 5 as next digit of the result. 
Result so far: 1655.0
Subtracting 2690 from 3186 leaves us with 496.
Grab the next digit (4) from the dividend, add it to 496, then carry on: 4964 / 538

Step 7:
When dividing 4964 by 538, we get 9 with a remainder of 122.
The number 9 becomes the next digit in our result. 
Result so far: 16559.0
If we subtract 4842 from 4964, we get 122.
Take the next digit (6) from the dividend and append it to 122, then repeat: 1226 / 538

On to step 8:
538 can be fit into 1226 2 times, resulting in a remainder of 150.
The next digit of our result is 2. 
Result so far: 165592.0
Subtract 1076 from 1226 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
538 goes into 1500 2 times with a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 165592.2
Subtract 1076 from 1500 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 10:
538 can be fit into 4240 7 times, resulting in a remainder of 474.
Write down 7 as next digit of the result. 
Result so far: 165592.27
If we subtract 3766 from 4240, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 11:
538 goes into 4740 8 times with a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 165592.278
If we subtract 4304 from 4740, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 12:
If we divide 4360 by 538, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 165592.2788
If we take 4304 away from 4360, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 165592.2788, with a leftover of 0.00056.
