Let's divide 53839963 by 432
We're looking to find how many times 432 goes into 53839963.

On to step 1:
5 divided by 432 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 432

Let's proceed to step 2:
If we divide 53 by 432, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 432

Advancing to step 3:
432 can be fit into 538 1 times, resulting in a remainder of 106.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 432 from 538, we get 106.
Take the next digit (3) from the dividend and append it to 106, then repeat: 1063 / 432

Step 4:
When dividing 1063 by 432, we get 2 with a remainder of 199.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 864 from 1063 and we're left with 199.
Fetch the next digit (9) from the dividend, attach it to 199 and continue: 1999 / 432

Moving on to step 5:
When dividing 1999 by 432, we get 4 with a remainder of 271.
Write down 4 as next digit of the result. 
Result so far: 124.0
The remainder is 271 after subtracting 1728 from 1999.
Grab the next digit (9) from the dividend, add it to 271, then carry on: 2719 / 432

On to step 6:
The number 432 fits into 2719 6 times, leaving a remainder of 127.
Put 6 as the next digit of the answer. 
Result so far: 1246.0
Subtracting 2592 from 2719 leaves us with 127.
Grab the next digit (6) from the dividend, add it to 127, then carry on: 1276 / 432

On to step 7:
The number 432 fits into 1276 2 times, leaving a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 12462.0
Deduct 864 from 1276 and we're left with 412.
Bring next digit (3) of the dividend behind the 412 and repeat the process: 4123 / 432

Moving on to step 8:
432 can be fit into 4123 9 times, resulting in a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 124629.0
The remainder is 235 after subtracting 3888 from 4123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 9:
2350 divided by 432 is 5 with a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 124629.5
Deduct 2160 from 2350 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
The number 432 fits into 1900 4 times, leaving a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 124629.54
If we take 1728 away from 1900, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
If we divide 1720 by 432, we get 3 and a remainder of 424.
Record the quotient 3 as the next digit in the result. 
Result so far: 124629.543
Subtracting 1296 from 1720 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 12:
4240 divided by 432 is 9 with a remainder of 352.
Use 9 as the next digit of our solution. 
Result so far: 124629.5439
If we take 3888 away from 4240, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 13:
3520 divided by 432 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 124629.54398
Subtracting 3456 from 3520 leaves us 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.

Going ahead to step 14:
If we divide 640 by 432, we get 1 and a remainder of 208.
Write down 1 as next digit of the result. 
Result so far: 124629.543981
Subtract 432 from 640 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
If we divide 2080 by 432, we get 4 and a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 124629.5439814
Subtract 1728 from 2080 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 16:
If we divide 3520 by 432, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 124629.54398148
Subtract 3456 from 3520 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 124629.54398148, with a leftover of 6.4e-08.
