We divide 51553731 by 357
We're looking to find how many times 357 goes into 51553731.

Step 1:
357 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
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 357

Going ahead to step 2:
51 divided by 357 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 357

Advancing to step 3:
The number 357 fits into 515 1 times, leaving a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 357 from 515, we get 158.
Take the next digit (5) from the dividend and append it to 158, then repeat: 1585 / 357

Going ahead to step 4:
357 can be fit into 1585 4 times, resulting in a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1428 from 1585 and we're left with 157.
Append the next digit (3) from the dividend to 157 and continue with: 1573 / 357

Moving on to step 5:
When dividing 1573 by 357, we get 4 with a remainder of 145.
The next digit of our result is 4. 
Result so far: 144.0
Deduct 1428 from 1573 and we're left with 145.
Fetch the next digit (7) from the dividend, attach it to 145 and continue: 1457 / 357

Going ahead to step 6:
1457 divided by 357 is 4 with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 1444.0
The remainder is 29 after subtracting 1428 from 1457.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 357

Let's proceed to step 7:
357 can be fit into 293 0 times, resulting in a remainder of 293.
Record the quotient 0 as the next digit in the result. 
Result so far: 14440.0
Deduct 0 from 293 and we're left with 293.
Bring next digit (1) of the dividend behind the 293 and repeat the process: 2931 / 357

Moving on to step 8:
2931 divided by 357 is 8 with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 144408.0
Subtracting 2856 from 2931 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
357 goes into 750 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 144408.2
If we subtract 714 from 750, 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 10:
360 divided by 357 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 144408.21
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
If we divide 30 by 357, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 144408.21
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 357 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 144408.21
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 144408.21, with a leftover of 0.003.
