We're dividing 15268212 by 403 
Our goal is to divide 15268212 by 403.

On to step 1:
The number 403 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 403

On to step 2:
The number 403 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 403

On to step 3:
If we divide 152 by 403, we get 0 and a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Append the next digit (6) from the dividend to 152 and continue with: 1526 / 403

Step 4:
1526 divided by 403 is 3 with a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1209 from 1526 to get 317.
Include the next digit (8) from the dividend after 317, then repeat: 3178 / 403

On to step 5:
403 can be fit into 3178 7 times, resulting in a remainder of 357.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 2821 from 3178 and we're left with 357.
Bring next digit (2) of the dividend behind the 357 and repeat the process: 3572 / 403

Going ahead to step 6:
403 can be fit into 3572 8 times, resulting in a remainder of 348.
Write down 8 as next digit of the result. 
Result so far: 378.0
Subtract 3224 from 3572 to get 348.
Include the next digit (1) from the dividend after 348, then repeat: 3481 / 403

Advancing to step 7:
If we divide 3481 by 403, we get 8 and a remainder of 257.
Record the quotient 8 as the next digit in the result. 
Result so far: 3788.0
Deduct 3224 from 3481 and we're left with 257.
Bring next digit (2) of the dividend behind the 257 and repeat the process: 2572 / 403

Advancing to step 8:
403 can be fit into 2572 6 times, resulting in a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 37886.0
Subtracting 2418 from 2572 leaves us 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.

On to step 9:
The number 403 fits into 1540 3 times, leaving a remainder of 331.
Put 3 as the next digit of the answer. 
Result so far: 37886.3
If we subtract 1209 from 1540, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 10:
3310 divided by 403 is 8 with a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 37886.38
If we take 3224 away from 3310, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
The number 403 fits into 860 2 times, leaving a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 37886.382
Deduct 806 from 860 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
The number 403 fits into 540 1 times, leaving a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 37886.3821
Subtracting 403 from 540 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 13:
When dividing 1370 by 403, we get 3 with a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 37886.38213
If we subtract 1209 from 1370, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 14:
403 goes into 1610 3 times with a remainder of 401.
Put 3 as the next digit of the answer. 
Result so far: 37886.382133
If we subtract 1209 from 1610, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

The quotient of the division is 37886.382133, and the remainder is 4.01e-05.
