Let's divide 51721440 by 368
Our goal is to divide 51721440 by 368.

Advancing to step 1:
368 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 368

Step 2:
368 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 368

Advancing to step 3:
If we divide 517 by 368, we get 1 and a remainder of 149.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 368 from 517 to get 149.
Append the next digit (2) from the dividend to 149 and continue with: 1492 / 368

Advancing to step 4:
1492 divided by 368 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1472 from 1492 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 368

On to step 5:
201 divided by 368 is 0 with a remainder of 201.
The next digit of our result is 0. 
Result so far: 140.0
Subtract 0 from 201 to get 201.
Append the next digit (4) from the dividend to 201 and continue with: 2014 / 368

On to step 6:
368 can be fit into 2014 5 times, resulting in a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 1405.0
If we take 1840 away from 2014, we end up with 174.
Take the next digit (4) from the dividend and append it to 174, then repeat: 1744 / 368

Moving on to step 7:
When dividing 1744 by 368, we get 4 with a remainder of 272.
The number 4 becomes the next digit in our result. 
Result so far: 14054.0
Subtracting 1472 from 1744 leaves us with 272.
Fetch the next digit (0) from the dividend, attach it to 272 and continue: 2720 / 368

On to step 8:
368 goes into 2720 7 times with a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 140547.0
Subtract 2576 from 2720 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 9:
368 can be fit into 1440 3 times, resulting in a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 140547.3
If we take 1104 away from 1440, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 10:
368 can be fit into 3360 9 times, resulting in a remainder of 48.
The next digit of our result is 9. 
Result so far: 140547.39
Subtracting 3312 from 3360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
The number 368 fits into 480 1 times, leaving a remainder of 112.
Write down 1 as next digit of the result. 
Result so far: 140547.391
Subtracting 368 from 480 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
368 can be fit into 1120 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 140547.3913
Subtract 1104 from 1120 to 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.

Step 13:
If we divide 160 by 368, we get 0 and a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 140547.3913
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
The number 368 fits into 1600 4 times, leaving a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 140547.391304
If we subtract 1472 from 1600, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
The number 368 fits into 1280 3 times, leaving a remainder of 176.
Use 3 as the next digit of our solution. 
Result so far: 140547.3913043
If we subtract 1104 from 1280, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 16:
If we divide 1760 by 368, we get 4 and a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 140547.39130434
The remainder is 288 after subtracting 1472 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 140547.39130434, with a leftover of 2.88e-07.
