53391297 divided by 357 
Let's see how many times 357 fits into 53391297.

Going ahead to step 1:
357 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 357

Moving on to step 2:
When dividing 53 by 357, we get 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 357

On to step 3:
357 can be fit into 533 1 times, resulting in a remainder of 176.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 357 from 533 to get 176.
Bring next digit (9) of the dividend behind the 176 and repeat the process: 1769 / 357

Let's proceed to step 4:
357 can be fit into 1769 4 times, resulting in a remainder of 341.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 1428 from 1769, we get 341.
Take the next digit (1) from the dividend and append it to 341, then repeat: 3411 / 357

Advancing to step 5:
357 can be fit into 3411 9 times, resulting in a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Subtracting 3213 from 3411 leaves us with 198.
Fetch the next digit (2) from the dividend, attach it to 198 and continue: 1982 / 357

Moving on to step 6:
When dividing 1982 by 357, we get 5 with a remainder of 197.
Write down 5 as next digit of the result. 
Result so far: 1495.0
If we take 1785 away from 1982, we end up with 197.
Append the next digit (9) from the dividend to 197 and continue with: 1979 / 357

Advancing to step 7:
1979 divided by 357 is 5 with a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 14955.0
Subtract 1785 from 1979 to get 194.
Include the next digit (7) from the dividend after 194, then repeat: 1947 / 357

Going ahead to step 8:
When dividing 1947 by 357, we get 5 with a remainder of 162.
Put 5 as the next digit of the answer. 
Result so far: 149555.0
Subtracting 1785 from 1947 leaves us 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.

Moving on to step 9:
The number 357 fits into 1620 4 times, leaving a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 149555.4
If we take 1428 away from 1620, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 10:
The number 357 fits into 1920 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 149555.45
If we take 1785 away from 1920, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 11:
1350 divided by 357 is 3 with a remainder of 279.
The number 3 becomes the next digit in our result. 
Result so far: 149555.453
Deduct 1071 from 1350 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 12:
357 can be fit into 2790 7 times, resulting in a remainder of 291.
Put 7 as the next digit of the answer. 
Result so far: 149555.4537
Deduct 2499 from 2790 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 13:
357 goes into 2910 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 149555.45378
Deduct 2856 from 2910 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
357 goes into 540 1 times with a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 149555.453781
If we subtract 357 from 540, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 15:
357 goes into 1830 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 149555.4537815
If we subtract 1785 from 1830, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 16:
357 goes into 450 1 times with a remainder of 93.
The next digit of our result is 1. 
Result so far: 149555.45378151
If we subtract 357 from 450, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The final outcome is 149555.45378151, with a leftover of 9.3e-08.
