We look at the division of 671661 by 89 
Let's see how many times 89 fits into 671661.

Advancing to step 1:
89 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 89

Moving on to step 2:
89 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 89

Going ahead to step 3:
If we divide 671 by 89, we get 7 and a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 623 from 671 leaves us with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 89

Moving on to step 4:
89 goes into 486 5 times with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 445 from 486 leaves us with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 89

Advancing to step 5:
If we divide 416 by 89, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 754.0
Deduct 356 from 416 and we're left with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 89

Advancing to step 6:
When dividing 601 by 89, we get 6 with a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 7546.0
Deduct 534 from 601 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
When dividing 670 by 89, we get 7 with a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 7546.7
If we take 623 away from 670, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 8:
89 goes into 470 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7546.75
If we subtract 445 from 470, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
When dividing 250 by 89, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 7546.752
The remainder is 72 after subtracting 178 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
89 goes into 720 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 7546.7528
Subtract 712 from 720 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 89 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 7546.7528
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 89, we get 8 and a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 7546.752808
If we take 712 away from 800, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
89 goes into 880 9 times with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 7546.7528089
If we take 801 away from 880, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 14:
The number 89 fits into 790 8 times, leaving a remainder of 78.
The next digit of our result is 8. 
Result so far: 7546.75280898
If we take 712 away from 790, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 7546.75280898, with a leftover of 7.8e-08.
