We divide 15215164 by 507
Our goal is to divide 15215164 by 507.

Step 1:
When dividing 1 by 507, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 507

On to step 2:
15 divided by 507 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 507

Moving on to step 3:
507 can be fit into 152 0 times, resulting in a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 152 leaves us with 152.
Include the next digit (1) from the dividend after 152, then repeat: 1521 / 507

Let's proceed to step 4:
The number 507 fits into 1521 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1521 from 1521 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 507

Let's proceed to step 5:
When dividing 5 by 507, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 507

Let's proceed to step 6:
When dividing 51 by 507, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 507

Let's proceed to step 7:
The number 507 fits into 516 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 3001.0
Subtracting 507 from 516 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 507

Step 8:
If we divide 94 by 507, we get 0 and a remainder of 94.
Write down 0 as next digit of the result. 
Result so far: 30010.0
The remainder is 94 after subtracting 0 from 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
507 can be fit into 940 1 times, resulting in a remainder of 433.
The number 1 becomes the next digit in our result. 
Result so far: 30010.1
If we take 507 away from 940, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 10:
507 goes into 4330 8 times with a remainder of 274.
Put 8 as the next digit of the answer. 
Result so far: 30010.18
Subtracting 4056 from 4330 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
When dividing 2740 by 507, we get 5 with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 30010.185
Deduct 2535 from 2740 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 12:
The number 507 fits into 2050 4 times, leaving a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 30010.1854
The remainder is 22 after subtracting 2028 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
When dividing 220 by 507, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 30010.1854
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
2200 divided by 507 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 30010.185404
Subtract 2028 from 2200 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 15:
507 can be fit into 1720 3 times, resulting in a remainder of 199.
Record the quotient 3 as the next digit in the result. 
Result so far: 30010.1854043
Deduct 1521 from 1720 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 16:
507 goes into 1990 3 times with a remainder of 469.
Use 3 as the next digit of our solution. 
Result so far: 30010.18540433
Deduct 1521 from 1990 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

The final outcome is 30010.18540433, with a leftover of 4.69e-07.
