We're dividing 402150 by 89 
We want to figure out the number of times 402150 can be divided by 89.

Let's proceed to step 1:
The number 89 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 89

Let's proceed to step 2:
If we divide 40 by 89, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 89

Moving on to step 3:
If we divide 402 by 89, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 356 from 402, we get 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 89

Going ahead to step 4:
461 divided by 89 is 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 16 after subtracting 445 from 461.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 89

Step 5:
When dividing 165 by 89, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 451.0
Subtract 89 from 165 to get 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 89

Moving on to step 6:
89 goes into 760 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4518.0
Subtract 712 from 760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
The number 89 fits into 480 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4518.5
Subtract 445 from 480 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
When dividing 350 by 89, we get 3 with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 4518.53
Deduct 267 from 350 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
The number 89 fits into 830 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 4518.539
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:
89 goes into 290 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 4518.5393
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.

Going ahead 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: 4518.53932
If we take 178 away from 230, we end up 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.

Advancing to step 12:
520 divided by 89 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 4518.539325
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.

Advancing to step 13:
When dividing 750 by 89, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 4518.5393258
Subtracting 712 from 750 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
380 divided by 89 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4518.53932584
If we subtract 356 from 380, we get 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 outcome is 4518.53932584, with a leftover of 2.4e-08.
