Let's divide 51939875 by 84
Let's see how many times 84 fits into 51939875.

Advancing to step 1:
If we divide 5 by 84, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 84

Going ahead to step 2:
51 divided by 84 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 84

On to step 3:
84 goes into 519 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 504 from 519 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 84

Step 4:
84 can be fit into 153 1 times, resulting in a remainder of 69.
The next digit of our result is 1. 
Result so far: 61.0
If we take 84 away from 153, we end up with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 84

On to step 5:
84 goes into 699 8 times with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 618.0
Subtracting 672 from 699 leaves us with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 84

Going ahead to step 6:
84 can be fit into 278 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 6183.0
The remainder is 26 after subtracting 252 from 278.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 84

Let's proceed to step 7:
The number 84 fits into 267 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 61833.0
If we subtract 252 from 267, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 84

Going ahead to step 8:
84 can be fit into 155 1 times, resulting in a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 618331.0
Deduct 84 from 155 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
If we divide 710 by 84, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 618331.8
Deduct 672 from 710 and we're left 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.

Going ahead to step 10:
84 can be fit into 380 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 618331.84
Deduct 336 from 380 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
If we divide 440 by 84, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 618331.845
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 618331.8452
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
320 divided by 84 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 618331.84523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
84 goes into 680 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 618331.845238
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
If we divide 80 by 84, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 618331.845238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
If we divide 800 by 84, we get 9 and a remainder of 44.
The next digit of our result is 9. 
Result so far: 618331.84523809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 618331.84523809 with a remainder of 4.4e-08.
