663279 ÷ 89 
We want to figure out the number of times 663279 can be divided by 89.

Step 1:
The number 89 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 89

Going ahead to step 2:
89 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 89

Step 3:
When dividing 663 by 89, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 623 from 663 and we're left with 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 89

Advancing to step 4:
When dividing 402 by 89, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 74.0
Deduct 356 from 402 and we're left with 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 89

Step 5:
If we divide 467 by 89, we get 5 and a remainder of 22.
The next digit of our result is 5. 
Result so far: 745.0
Deduct 445 from 467 and we're left with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 89

Step 6:
When dividing 229 by 89, we get 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 7452.0
If we subtract 178 from 229, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
510 divided by 89 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7452.5
If we take 445 away from 510, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
89 can be fit into 650 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 7452.57
If we take 623 away from 650, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
If we divide 270 by 89, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 7452.573
Deduct 267 from 270 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 89 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 7452.573
Deduct 0 from 30 and we're left with 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 11:
When dividing 300 by 89, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 7452.57303
The remainder is 33 after subtracting 267 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
330 divided by 89 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 7452.573033
Subtract 267 from 330 to get 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 7452.573033, with a leftover of 6.3e-06.
