We look at the division of 66725697 by 89 
Let's see how many times 89 fits into 66725697.

Going ahead to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 89

Going ahead to step 2:
89 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 89

Let's proceed to step 3:
When dividing 667 by 89, we get 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 623 from 667 to get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 89

Advancing to step 4:
When dividing 442 by 89, we get 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 356 from 442 leaves us with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 89

Step 5:
The number 89 fits into 865 9 times, leaving a remainder of 64.
The next digit of our result is 9. 
Result so far: 749.0
If we take 801 away from 865, we end up with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 89

Advancing to step 6:
The number 89 fits into 646 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 7497.0
Subtract 623 from 646 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 89

Moving on to step 7:
If we divide 239 by 89, we get 2 and a remainder of 61.
The next digit of our result is 2. 
Result so far: 74972.0
Deduct 178 from 239 and we're left with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 89

Moving on to step 8:
89 can be fit into 617 6 times, resulting in a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 749726.0
Subtract 534 from 617 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
The number 89 fits into 830 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 749726.9
Subtracting 801 from 830 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
If we divide 290 by 89, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 749726.93
Subtracting 267 from 290 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
89 goes into 230 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 749726.932
Deduct 178 from 230 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
89 can be fit into 520 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 749726.9325
Subtract 445 from 520 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
89 goes into 750 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 749726.93258
The remainder is 38 after subtracting 712 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
89 goes into 380 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 749726.932584
If we take 356 away from 380, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
The number 89 fits into 240 2 times, leaving a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 749726.9325842
The remainder is 62 after subtracting 178 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 16:
89 can be fit into 620 6 times, resulting in a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 749726.93258426
Deduct 534 from 620 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 749726.93258426 and a remainder of 8.6e-08.
