53419586 ÷ 517 
Let's see how many times 517 fits into 53419586.

On to step 1:
If we divide 5 by 517, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 517

Moving on to step 2:
517 goes into 53 0 times 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.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 517

Step 3:
If we divide 534 by 517, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 517 from 534.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 517

Advancing to step 4:
When dividing 171 by 517, we get 0 with a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 171 leaves us with 171.
Bring next digit (9) of the dividend behind the 171 and repeat the process: 1719 / 517

Going ahead to step 5:
1719 divided by 517 is 3 with a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we subtract 1551 from 1719, we get 168.
Take the next digit (5) from the dividend and append it to 168, then repeat: 1685 / 517

Moving on to step 6:
When dividing 1685 by 517, we get 3 with a remainder of 134.
Write down 3 as next digit of the result. 
Result so far: 1033.0
If we take 1551 away from 1685, we end up with 134.
Append the next digit (8) from the dividend to 134 and continue with: 1348 / 517

Moving on to step 7:
If we divide 1348 by 517, we get 2 and a remainder of 314.
The next digit of our result is 2. 
Result so far: 10332.0
Subtract 1034 from 1348 to get 314.
Bring next digit (6) of the dividend behind the 314 and repeat the process: 3146 / 517

Moving on to step 8:
The number 517 fits into 3146 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 103326.0
Subtracting 3102 from 3146 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
517 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 103326.0
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 10:
4400 divided by 517 is 8 with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 103326.08
Subtracting 4136 from 4400 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 11:
517 can be fit into 2640 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 103326.085
If we take 2585 away from 2640, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
The number 517 fits into 550 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 103326.0851
Subtracting 517 from 550 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
The number 517 fits into 330 0 times, leaving a remainder of 330.
The next digit of our result is 0. 
Result so far: 103326.0851
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 14:
If we divide 3300 by 517, we get 6 and a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 103326.085106
If we subtract 3102 from 3300, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 15:
517 goes into 1980 3 times with a remainder of 429.
Write down 3 as next digit of the result. 
Result so far: 103326.0851063
Subtracting 1551 from 1980 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 16:
517 can be fit into 4290 8 times, resulting in a remainder of 154.
Record the quotient 8 as the next digit in the result. 
Result so far: 103326.08510638
Deduct 4136 from 4290 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 103326.08510638 with a remainder of 1.54e-07.
