Let's divide 50146521 by 345
Our goal is to divide 50146521 by 345.

Moving on to step 1:
The number 345 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 345

On to step 2:
345 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 345

Let's proceed to step 3:
345 can be fit into 501 1 times, resulting in a remainder of 156.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 345 from 501 leaves us with 156.
Bring next digit (4) of the dividend behind the 156 and repeat the process: 1564 / 345

Let's proceed to step 4:
The number 345 fits into 1564 4 times, leaving a remainder of 184.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1380 from 1564 leaves us with 184.
Append the next digit (6) from the dividend to 184 and continue with: 1846 / 345

Going ahead to step 5:
345 goes into 1846 5 times with a remainder of 121.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Deduct 1725 from 1846 and we're left with 121.
Include the next digit (5) from the dividend after 121, then repeat: 1215 / 345

Going ahead to step 6:
The number 345 fits into 1215 3 times, leaving a remainder of 180.
Write down 3 as next digit of the result. 
Result so far: 1453.0
The remainder is 180 after subtracting 1035 from 1215.
Grab the next digit (2) from the dividend, add it to 180, then carry on: 1802 / 345

Going ahead to step 7:
If we divide 1802 by 345, we get 5 and a remainder of 77.
Use 5 as the next digit of our solution. 
Result so far: 14535.0
If we subtract 1725 from 1802, we get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 345

Let's proceed to step 8:
When dividing 771 by 345, we get 2 with a remainder of 81.
The next digit of our result is 2. 
Result so far: 145352.0
If we subtract 690 from 771, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
810 divided by 345 is 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 145352.2
If we take 690 away from 810, we end up 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.

Going ahead to step 10:
If we divide 1200 by 345, we get 3 and a remainder of 165.
The number 3 becomes the next digit in our result. 
Result so far: 145352.23
Deduct 1035 from 1200 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
1650 divided by 345 is 4 with a remainder of 270.
Put 4 as the next digit of the answer. 
Result so far: 145352.234
Subtracting 1380 from 1650 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 12:
2700 divided by 345 is 7 with a remainder of 285.
Record the quotient 7 as the next digit in the result. 
Result so far: 145352.2347
Deduct 2415 from 2700 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 13:
When dividing 2850 by 345, we get 8 with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 145352.23478
If we subtract 2760 from 2850, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
345 can be fit into 900 2 times, resulting in a remainder of 210.
Use 2 as the next digit of our solution. 
Result so far: 145352.234782
If we take 690 away from 900, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 15:
345 goes into 2100 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 145352.2347826
If we take 2070 away from 2100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
When dividing 300 by 345, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 145352.2347826
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 145352.2347826 and a remainder of 3e-07.
