We're dividing 51073873 by 338 
We're looking to find how many times 338 goes into 51073873.

Let's proceed to step 1:
338 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
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 338

Going ahead to step 2:
338 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
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 338

Let's proceed to step 3:
338 goes into 510 1 times with a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 338 from 510 and we're left with 172.
Fetch the next digit (7) from the dividend, attach it to 172 and continue: 1727 / 338

Going ahead to step 4:
The number 338 fits into 1727 5 times, leaving a remainder of 37.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 37 after subtracting 1690 from 1727.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 338

Step 5:
338 can be fit into 373 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we subtract 338 from 373, we get 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 338

Moving on to step 6:
If we divide 358 by 338, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1511.0
The remainder is 20 after subtracting 338 from 358.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 338

On to step 7:
When dividing 207 by 338, we get 0 with a remainder of 207.
The number 0 becomes the next digit in our result. 
Result so far: 15110.0
Subtracting 0 from 207 leaves us with 207.
Include the next digit (3) from the dividend after 207, then repeat: 2073 / 338

Let's proceed to step 8:
338 can be fit into 2073 6 times, resulting in a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 151106.0
If we take 2028 away from 2073, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 338, we get 1 with a remainder of 112.
The next digit of our result is 1. 
Result so far: 151106.1
Deduct 338 from 450 and we're left 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 10:
338 can be fit into 1120 3 times, resulting in a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 151106.13
The remainder is 106 after subtracting 1014 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 11:
338 can be fit into 1060 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 151106.133
The remainder is 46 after subtracting 1014 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 151106.133 with a remainder of 0.0046.
