We look at the division of 51800647 by 357 
Let's see how many times 357 fits into 51800647.

Going ahead to step 1:
The number 357 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 357

Moving on to step 2:
357 goes into 51 0 times with 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.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 357

Going ahead to step 3:
357 can be fit into 518 1 times, resulting in a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 357 from 518 leaves us with 161.
Take the next digit (0) from the dividend and append it to 161, then repeat: 1610 / 357

Going ahead to step 4:
357 can be fit into 1610 4 times, resulting in a remainder of 182.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1428 from 1610 leaves us with 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 357

Moving on to step 5:
357 can be fit into 1820 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtracting 1785 from 1820 leaves us with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 357

Let's proceed to step 6:
When dividing 356 by 357, we get 0 with a remainder of 356.
Use 0 as the next digit of our solution. 
Result so far: 1450.0
The remainder is 356 after subtracting 0 from 356.
Grab the next digit (4) from the dividend, add it to 356, then carry on: 3564 / 357

Let's proceed to step 7:
The number 357 fits into 3564 9 times, leaving a remainder of 351.
Record the quotient 9 as the next digit in the result. 
Result so far: 14509.0
Deduct 3213 from 3564 and we're left with 351.
Include the next digit (7) from the dividend after 351, then repeat: 3517 / 357

Moving on to step 8:
When dividing 3517 by 357, we get 9 with a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 145099.0
Deduct 3213 from 3517 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
3040 divided by 357 is 8 with a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 145099.8
Deduct 2856 from 3040 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 10:
357 can be fit into 1840 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 145099.85
Subtract 1785 from 1840 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 11:
The number 357 fits into 550 1 times, leaving a remainder of 193.
The next digit of our result is 1. 
Result so far: 145099.851
If we subtract 357 from 550, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 12:
1930 divided by 357 is 5 with a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 145099.8515
Subtract 1785 from 1930 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 13:
If we divide 1450 by 357, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 145099.85154
If we take 1428 away from 1450, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
357 goes into 220 0 times with a remainder of 220.
The next digit of our result is 0. 
Result so far: 145099.85154
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
If we divide 2200 by 357, we get 6 and a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 145099.8515406
Subtracting 2142 from 2200 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
When dividing 580 by 357, we get 1 with a remainder of 223.
The next digit of our result is 1. 
Result so far: 145099.85154061
Subtract 357 from 580 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

The final result is 145099.85154061 with a remainder of 2.23e-07.
