63157102 ÷ 513 
Let's see how many times 513 fits into 63157102.

Advancing to step 1:
513 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 513

Moving on to step 2:
If we divide 63 by 513, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 513

Going ahead to step 3:
If we divide 631 by 513, we get 1 and a remainder of 118.
The next digit of our result is 1. 
Result so far: 1.0
If we take 513 away from 631, we end up with 118.
Take the next digit (5) from the dividend and append it to 118, then repeat: 1185 / 513

Going ahead to step 4:
1185 divided by 513 is 2 with a remainder of 159.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1026 from 1185 and we're left with 159.
Append the next digit (7) from the dividend to 159 and continue with: 1597 / 513

Moving on to step 5:
The number 513 fits into 1597 3 times, leaving a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtract 1539 from 1597 to get 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 513

Step 6:
581 divided by 513 is 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1231.0
The remainder is 68 after subtracting 513 from 581.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 513

Moving on to step 7:
513 goes into 680 1 times with a remainder of 167.
The next digit of our result is 1. 
Result so far: 12311.0
The remainder is 167 after subtracting 513 from 680.
Fetch the next digit (2) from the dividend, attach it to 167 and continue: 1672 / 513

Advancing to step 8:
1672 divided by 513 is 3 with a remainder of 133.
Use 3 as the next digit of our solution. 
Result so far: 123113.0
The remainder is 133 after subtracting 1539 from 1672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 9:
513 can be fit into 1330 2 times, resulting in a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 123113.2
If we subtract 1026 from 1330, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 10:
513 can be fit into 3040 5 times, resulting in a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 123113.25
Deduct 2565 from 3040 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 11:
If we divide 4750 by 513, we get 9 and a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 123113.259
If we subtract 4617 from 4750, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 12:
513 can be fit into 1330 2 times, resulting in a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 123113.2592
Deduct 1026 from 1330 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.

Step 13:
If we divide 3040 by 513, we get 5 and a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 123113.25925
Deduct 2565 from 3040 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 14:
If we divide 4750 by 513, we get 9 and a remainder of 133.
Record the quotient 9 as the next digit in the result. 
Result so far: 123113.259259
Deduct 4617 from 4750 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 15:
The number 513 fits into 1330 2 times, leaving a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 123113.2592592
If we subtract 1026 from 1330, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 16:
3040 divided by 513 is 5 with a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 123113.25925925
The remainder is 475 after subtracting 2565 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The final outcome is 123113.25925925, with a leftover of 4.75e-07.
