Let's divide 123642 by 89
Let's see how many times 89 fits into 123642.

Let's proceed to step 1:
89 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 89

On to step 2:
12 divided by 89 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 89

Let's proceed to step 3:
89 goes into 123 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 89 from 123 and we're left with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 89

Going ahead to step 4:
89 can be fit into 346 3 times, resulting in a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 79 after subtracting 267 from 346.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 89

Advancing to step 5:
794 divided by 89 is 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we subtract 712 from 794, we get 82.
Append the next digit (2) from the dividend to 82 and continue with: 822 / 89

Going ahead to step 6:
The number 89 fits into 822 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 1389.0
If we take 801 away from 822, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
89 can be fit into 210 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 1389.2
If we take 178 away from 210, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
The number 89 fits into 320 3 times, leaving a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 1389.23
Subtract 267 from 320 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
89 can be fit into 530 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 1389.235
Subtracting 445 from 530 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
89 goes into 850 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 1389.2359
Subtracting 801 from 850 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
The number 89 fits into 490 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 1389.23595
If we take 445 away from 490, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
When dividing 450 by 89, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1389.235955
Deduct 445 from 450 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 1389.235955, with a leftover of 5e-07.
