We're dividing 51511037 by 373 
Our goal is to divide 51511037 by 373.

On to step 1:
373 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 373

Step 2:
When dividing 51 by 373, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 373

Step 3:
373 goes into 515 1 times with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 373 from 515 and we're left with 142.
Append the next digit (1) from the dividend to 142 and continue with: 1421 / 373

Step 4:
373 goes into 1421 3 times with a remainder of 302.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 302 after subtracting 1119 from 1421.
Bring next digit (1) of the dividend behind the 302 and repeat the process: 3021 / 373

On to step 5:
If we divide 3021 by 373, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 2984 away from 3021, we end up with 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 373

On to step 6:
When dividing 370 by 373, we get 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 1380.0
The remainder is 370 after subtracting 0 from 370.
Include the next digit (3) from the dividend after 370, then repeat: 3703 / 373

On to step 7:
373 can be fit into 3703 9 times, resulting in a remainder of 346.
Write down 9 as next digit of the result. 
Result so far: 13809.0
Subtract 3357 from 3703 to get 346.
Include the next digit (7) from the dividend after 346, then repeat: 3467 / 373

Let's proceed to step 8:
373 goes into 3467 9 times with a remainder of 110.
The next digit of our result is 9. 
Result so far: 138099.0
Subtracting 3357 from 3467 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 9:
When dividing 1100 by 373, we get 2 with a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 138099.2
The remainder is 354 after subtracting 746 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 10:
3540 divided by 373 is 9 with a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 138099.29
If we subtract 3357 from 3540, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 11:
1830 divided by 373 is 4 with a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 138099.294
If we subtract 1492 from 1830, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 12:
The number 373 fits into 3380 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 138099.2949
If we take 3357 away from 3380, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
When dividing 230 by 373, we get 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 138099.2949
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 14:
2300 divided by 373 is 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 138099.294906
Deduct 2238 from 2300 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 15:
When dividing 620 by 373, we get 1 with a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 138099.2949061
The remainder is 247 after subtracting 373 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 16:
If we divide 2470 by 373, we get 6 and a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 138099.29490616
Subtract 2238 from 2470 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

After the division, we end up with 138099.29490616 and a remainder of 2.32e-07.
