We're dividing 642539 by 89 
We're looking to find how many times 89 goes into 642539.

Going ahead to step 1:
When dividing 6 by 89, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 89

Step 2:
When dividing 64 by 89, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 89

Going ahead to step 3:
When dividing 642 by 89, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 623 from 642 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 89

Moving on to step 4:
89 goes into 195 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 72.0
The remainder is 17 after subtracting 178 from 195.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 89

Let's proceed to step 5:
When dividing 173 by 89, we get 1 with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 721.0
Subtracting 89 from 173 leaves us with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 89

Step 6:
89 can be fit into 849 9 times, resulting in a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 7219.0
If we take 801 away from 849, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 89 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 7219.5
If we take 445 away from 480, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 89, we get 3 and a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 7219.53
Subtract 267 from 350 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.

Moving on to step 9:
89 goes into 830 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 7219.539
Deduct 801 from 830 and we're left 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.

Step 10:
89 goes into 290 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 7219.5393
Subtract 267 from 290 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
When dividing 230 by 89, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 7219.53932
The remainder is 52 after subtracting 178 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
89 can be fit into 520 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 7219.539325
Subtracting 445 from 520 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
89 goes into 750 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 7219.5393258
Subtract 712 from 750 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
380 divided by 89 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 7219.53932584
Deduct 356 from 380 and we're left 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.

The final result is 7219.53932584 with a remainder of 2.4e-08.
