Let's divide 76339622 by 513
Our goal is to divide 76339622 by 513.

On to step 1:
513 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 513

Step 2:
513 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 513

Advancing to step 3:
When dividing 763 by 513, we get 1 with a remainder of 250.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 513 from 763, we get 250.
Grab the next digit (3) from the dividend, add it to 250, then carry on: 2503 / 513

On to step 4:
2503 divided by 513 is 4 with a remainder of 451.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2052 from 2503 to get 451.
Grab the next digit (9) from the dividend, add it to 451, then carry on: 4519 / 513

Going ahead to step 5:
513 goes into 4519 8 times with a remainder of 415.
The next digit of our result is 8. 
Result so far: 148.0
If we take 4104 away from 4519, we end up with 415.
Grab the next digit (6) from the dividend, add it to 415, then carry on: 4156 / 513

Step 6:
When dividing 4156 by 513, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 1488.0
Subtracting 4104 from 4156 leaves us with 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 513

Advancing to step 7:
The number 513 fits into 522 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 14881.0
The remainder is 9 after subtracting 513 from 522.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 513

On to step 8:
513 can be fit into 92 0 times, resulting in a remainder of 92.
Use 0 as the next digit of our solution. 
Result so far: 148810.0
Subtract 0 from 92 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 9:
If we divide 920 by 513, we get 1 and a remainder of 407.
Put 1 as the next digit of the answer. 
Result so far: 148810.1
Subtracting 513 from 920 leaves us with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 10:
513 goes into 4070 7 times with a remainder of 479.
Put 7 as the next digit of the answer. 
Result so far: 148810.17
If we subtract 3591 from 4070, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 11:
4790 divided by 513 is 9 with a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 148810.179
Subtract 4617 from 4790 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 12:
513 can be fit into 1730 3 times, resulting in a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 148810.1793
Deduct 1539 from 1730 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 13:
If we divide 1910 by 513, we get 3 and a remainder of 371.
Write down 3 as next digit of the result. 
Result so far: 148810.17933
Subtracting 1539 from 1910 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final result is 148810.17933 with a remainder of 0.000371.
