Let's divide 101689 by 89
Let's see how many times 89 fits into 101689.

Advancing to step 1:
89 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 89

Going ahead to step 2:
10 divided by 89 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 89

Going ahead to step 3:
When dividing 101 by 89, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 89 away from 101, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 89

Step 4:
When dividing 126 by 89, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 89 from 126 leaves us with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 89

Step 5:
89 can be fit into 378 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 356 from 378 to get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 89

Moving on to step 6:
229 divided by 89 is 2 with a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 1142.0
The remainder is 51 after subtracting 178 from 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
89 can be fit into 510 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 1142.5
Deduct 445 from 510 and we're left 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 goes into 650 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 1142.57
Subtract 623 from 650 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
89 goes into 270 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1142.573
Subtract 267 from 270 to get 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:
If we divide 30 by 89, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1142.573
If we take 0 away from 30, we end up 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.

Going ahead to step 11:
300 divided by 89 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 1142.57303
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.

Going ahead to step 12:
If we divide 330 by 89, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 1142.573033
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 result is 1142.573033 with a remainder of 6.3e-06.
