We're dividing 51032529 by 345 
We want to divide 51032529 by 345.

Step 1:
The number 345 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 345

Going ahead to step 2:
345 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 345

Step 3:
The number 345 fits into 510 1 times, leaving a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 345 away from 510, we end up with 165.
Grab the next digit (3) from the dividend, add it to 165, then carry on: 1653 / 345

On to step 4:
345 goes into 1653 4 times with a remainder of 273.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1380 from 1653 to get 273.
Fetch the next digit (2) from the dividend, attach it to 273 and continue: 2732 / 345

Advancing to step 5:
345 can be fit into 2732 7 times, resulting in a remainder of 317.
Put 7 as the next digit of the answer. 
Result so far: 147.0
The remainder is 317 after subtracting 2415 from 2732.
Append the next digit (5) from the dividend to 317 and continue with: 3175 / 345

Advancing to step 6:
345 can be fit into 3175 9 times, resulting in a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 1479.0
The remainder is 70 after subtracting 3105 from 3175.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 345

On to step 7:
345 can be fit into 702 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 14792.0
If we take 690 away from 702, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 345

Let's proceed to step 8:
345 goes into 129 0 times with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 147920.0
Deduct 0 from 129 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 9:
If we divide 1290 by 345, we get 3 and a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 147920.3
If we take 1035 away from 1290, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 10:
If we divide 2550 by 345, we get 7 and a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 147920.37
If we subtract 2415 from 2550, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
345 can be fit into 1350 3 times, resulting in a remainder of 315.
The number 3 becomes the next digit in our result. 
Result so far: 147920.373
Subtract 1035 from 1350 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 12:
If we divide 3150 by 345, we get 9 and a remainder of 45.
The next digit of our result is 9. 
Result so far: 147920.3739
If we take 3105 away from 3150, 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.

Let's proceed to step 13:
345 can be fit into 450 1 times, resulting in a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 147920.37391
If we take 345 away from 450, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 14:
1050 divided by 345 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 147920.373913
Subtract 1035 from 1050 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 15:
The number 345 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 147920.373913
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
345 goes into 1500 4 times with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 147920.37391304
Subtracting 1380 from 1500 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 147920.37391304 with a remainder of 1.2e-07.
