638789 ÷ 89 
We want to figure out the number of times 638789 can be divided by 89.

On to step 1:
When dividing 6 by 89, we get 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 (3) of the dividend behind the 6 and repeat the process: 63 / 89

Let's proceed to step 2:
When dividing 63 by 89, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 89

Moving on to step 3:
89 can be fit into 638 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 623 from 638, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 89

Moving on to step 4:
When dividing 157 by 89, we get 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 68 after subtracting 89 from 157.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 89

Advancing to step 5:
If we divide 688 by 89, we get 7 and a remainder of 65.
The next digit of our result is 7. 
Result so far: 717.0
Deduct 623 from 688 and we're left with 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 89

Advancing to step 6:
89 goes into 659 7 times with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7177.0
Subtracting 623 from 659 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 89 fits into 360 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 7177.4
If we subtract 356 from 360, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 89 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7177.4
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
89 goes into 400 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 7177.404
Subtracting 356 from 400 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
89 goes into 440 4 times with a remainder of 84.
The next digit of our result is 4. 
Result so far: 7177.4044
If we take 356 away from 440, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 7177.4044, and the remainder is 0.00084.
