We divide 840172 by 53
We want to divide 840172 by 53.

Step 1:
8 divided by 53 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 53

On to step 2:
84 divided by 53 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 53 from 84 to get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 53

Moving on to step 3:
If we divide 310 by 53, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 265 from 310 leaves us with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 53

Step 4:
451 divided by 53 is 8 with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we take 424 away from 451, we end up with 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 53

Step 5:
53 goes into 277 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 1585.0
Subtract 265 from 277 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 53

Let's proceed to step 6:
53 can be fit into 122 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 15852.0
If we subtract 106 from 122, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 53 fits into 160 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 15852.3
Deduct 159 from 160 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
10 divided by 53 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 15852.3
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 53, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 15852.301
Deduct 53 from 100 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
The number 53 fits into 470 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 15852.3018
If we take 424 away from 470, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
53 can be fit into 460 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 15852.30188
If we subtract 424 from 460, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 15852.30188 with a balance of 3.6e-05.
