We're dividing 51139902 by 329 
Let's see how many times 329 fits into 51139902.

Let's proceed to step 1:
329 can be fit into 5 0 times, resulting in 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.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 329

Advancing to step 2:
329 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 329

Moving on to step 3:
329 goes into 511 1 times with a remainder of 182.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 182 after subtracting 329 from 511.
Bring next digit (3) of the dividend behind the 182 and repeat the process: 1823 / 329

Step 4:
When dividing 1823 by 329, we get 5 with a remainder of 178.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 1645 from 1823 leaves us with 178.
Append the next digit (9) from the dividend to 178 and continue with: 1789 / 329

Moving on to step 5:
329 can be fit into 1789 5 times, resulting in a remainder of 144.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we subtract 1645 from 1789, we get 144.
Append the next digit (9) from the dividend to 144 and continue with: 1449 / 329

On to step 6:
When dividing 1449 by 329, we get 4 with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 1554.0
If we take 1316 away from 1449, we end up with 133.
Take the next digit (0) from the dividend and append it to 133, then repeat: 1330 / 329

Advancing to step 7:
329 goes into 1330 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 15544.0
Deduct 1316 from 1330 and we're left with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 329

On to step 8:
If we divide 142 by 329, we get 0 and a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 155440.0
The remainder is 142 after subtracting 0 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 9:
If we divide 1420 by 329, we get 4 and a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 155440.4
If we subtract 1316 from 1420, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
If we divide 1040 by 329, we get 3 and a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 155440.43
The remainder is 53 after subtracting 987 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
530 divided by 329 is 1 with a remainder of 201.
Write down 1 as next digit of the result. 
Result so far: 155440.431
If we subtract 329 from 530, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 12:
329 can be fit into 2010 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 155440.4316
If we subtract 1974 from 2010, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 329 fits into 360 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 155440.43161
If we subtract 329 from 360, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
310 divided by 329 is 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 155440.43161
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 15:
The number 329 fits into 3100 9 times, leaving a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 155440.4316109
The remainder is 139 after subtracting 2961 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 16:
When dividing 1390 by 329, we get 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 155440.43161094
If we take 1316 away from 1390, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 155440.43161094 with a balance of 7.4e-08.
