We look at the division of 40250509 by 84 
We're looking to find how many times 84 goes into 40250509.

Going ahead to step 1:
4 divided by 84 is 0 with 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.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 84

Moving on to step 2:
When dividing 40 by 84, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 84

Step 3:
The number 84 fits into 402 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 336 from 402 and we're left with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 84

On to step 4:
665 divided by 84 is 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 588 from 665 to get 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 84

Moving on to step 5:
84 goes into 770 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Deduct 756 from 770 and we're left with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 84

On to step 6:
When dividing 145 by 84, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 4791.0
The remainder is 61 after subtracting 84 from 145.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 84

Let's proceed to step 7:
The number 84 fits into 610 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 47917.0
The remainder is 22 after subtracting 588 from 610.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 84

Moving on to step 8:
The number 84 fits into 229 2 times, leaving a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 479172.0
Subtracting 168 from 229 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
84 can be fit into 610 7 times, resulting in a remainder of 22.
The next digit of our result is 7. 
Result so far: 479172.7
If we subtract 588 from 610, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
84 goes into 220 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 479172.72
Deduct 168 from 220 and we're left 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.

Let's proceed to step 11:
If we divide 520 by 84, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 479172.726
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
When dividing 160 by 84, we get 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 479172.7261
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 479172.72619
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
84 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 479172.72619
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
84 goes into 400 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 479172.7261904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
If we divide 640 by 84, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 479172.72619047
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 479172.72619047, and the remainder is 5.2e-08.
