We're dividing 51807285 by 343 
We want to divide 51807285 by 343.

Advancing to step 1:
343 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
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 343

On to step 2:
If we divide 51 by 343, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 343

Going ahead to step 3:
If we divide 518 by 343, we get 1 and a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 343 from 518 to get 175.
Append the next digit (0) from the dividend to 175 and continue with: 1750 / 343

Moving on to step 4:
343 can be fit into 1750 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 1715 from 1750 and we're left with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 343

Moving on to step 5:
When dividing 357 by 343, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 343 from 357 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 343

Let's proceed to step 6:
The number 343 fits into 142 0 times, leaving a remainder of 142.
The number 0 becomes the next digit in our result. 
Result so far: 1510.0
If we subtract 0 from 142, we get 142.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 343

Going ahead to step 7:
The number 343 fits into 1428 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 15104.0
Subtract 1372 from 1428 to get 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 343

On to step 8:
When dividing 565 by 343, we get 1 with a remainder of 222.
The next digit of our result is 1. 
Result so far: 151041.0
The remainder is 222 after subtracting 343 from 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 9:
2220 divided by 343 is 6 with a remainder of 162.
The number 6 becomes the next digit in our result. 
Result so far: 151041.6
If we take 2058 away from 2220, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 10:
When dividing 1620 by 343, we get 4 with a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 151041.64
If we subtract 1372 from 1620, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 11:
The number 343 fits into 2480 7 times, leaving a remainder of 79.
The next digit of our result is 7. 
Result so far: 151041.647
If we take 2401 away from 2480, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 12:
The number 343 fits into 790 2 times, leaving a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 151041.6472
Subtracting 686 from 790 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
1040 divided by 343 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 151041.64723
The remainder is 11 after subtracting 1029 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
If we divide 110 by 343, we get 0 and a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 151041.64723
Subtracting 0 from 110 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.

Moving on to step 15:
If we divide 1100 by 343, we get 3 and a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 151041.6472303
If we take 1029 away from 1100, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 16:
When dividing 710 by 343, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 151041.64723032
The remainder is 24 after subtracting 686 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 151041.64723032, and the remainder is 2.4e-08.
