63520137 ÷ 357 
We want to figure out the number of times 63520137 can be divided by 357.

Step 1:
When dividing 6 by 357, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 357

Advancing to step 2:
357 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 357

Step 3:
The number 357 fits into 635 1 times, leaving a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 357 away from 635, we end up with 278.
Include the next digit (2) from the dividend after 278, then repeat: 2782 / 357

Moving on to step 4:
If we divide 2782 by 357, we get 7 and a remainder of 283.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 283 after subtracting 2499 from 2782.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 357

Step 5:
357 goes into 2830 7 times with a remainder of 331.
Write down 7 as next digit of the result. 
Result so far: 177.0
The remainder is 331 after subtracting 2499 from 2830.
Take the next digit (1) from the dividend and append it to 331, then repeat: 3311 / 357

Let's proceed to step 6:
The number 357 fits into 3311 9 times, leaving a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 1779.0
Subtracting 3213 from 3311 leaves us with 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 357

Step 7:
357 goes into 983 2 times with a remainder of 269.
The next digit of our result is 2. 
Result so far: 17792.0
Subtract 714 from 983 to get 269.
Grab the next digit (7) from the dividend, add it to 269, then carry on: 2697 / 357

On to step 8:
If we divide 2697 by 357, we get 7 and a remainder of 198.
Use 7 as the next digit of our solution. 
Result so far: 177927.0
Deduct 2499 from 2697 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
357 can be fit into 1980 5 times, resulting in a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 177927.5
If we take 1785 away from 1980, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 10:
If we divide 1950 by 357, we get 5 and a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 177927.55
Subtract 1785 from 1950 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 177927.55, and the remainder is 0.165.
