839978 ÷ 53 
Our goal is to divide 839978 by 53.

Going ahead to step 1:
53 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 53

Step 2:
53 can be fit into 83 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 53 from 83 and we're left with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 53

Let's proceed to step 3:
If we divide 309 by 53, we get 5 and a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 265 from 309 to get 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 53

Let's proceed to step 4:
449 divided by 53 is 8 with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 158.0
The remainder is 25 after subtracting 424 from 449.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 53

On to step 5:
257 divided by 53 is 4 with a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 1584.0
Deduct 212 from 257 and we're left with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 53

Let's proceed to step 6:
The number 53 fits into 458 8 times, leaving a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 15848.0
If we subtract 424 from 458, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
When dividing 340 by 53, we get 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 15848.6
If we subtract 318 from 340, 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.

Advancing to step 8:
The number 53 fits into 220 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 15848.64
The remainder is 8 after subtracting 212 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 53, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 15848.641
The remainder is 27 after subtracting 53 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
If we divide 270 by 53, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15848.6415
Subtracting 265 from 270 leaves us 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.

Going ahead to step 11:
53 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 15848.6415
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
If we divide 500 by 53, we get 9 and a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 15848.641509
If we subtract 477 from 500, we 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 13:
53 goes into 230 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 15848.6415094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
When dividing 180 by 53, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 15848.64150943
Deduct 159 from 180 and we're left 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.

In conclusion, the division gives 15848.64150943 with a balance of 2.1e-08.
