We look at the division of 57478215 by 903 
We want to figure out the number of times 57478215 can be divided by 903.

Advancing to step 1:
903 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 903

On to step 2:
If we divide 57 by 903, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 903

On to step 3:
574 divided by 903 is 0 with a remainder of 574.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 574 and we're left with 574.
Grab the next digit (7) from the dividend, add it to 574, then carry on: 5747 / 903

Step 4:
If we divide 5747 by 903, we get 6 and a remainder of 329.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 5418 from 5747 leaves us with 329.
Include the next digit (8) from the dividend after 329, then repeat: 3298 / 903

Advancing to step 5:
903 can be fit into 3298 3 times, resulting in a remainder of 589.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 589 after subtracting 2709 from 3298.
Take the next digit (2) from the dividend and append it to 589, then repeat: 5892 / 903

Advancing to step 6:
The number 903 fits into 5892 6 times, leaving a remainder of 474.
Write down 6 as next digit of the result. 
Result so far: 636.0
Subtracting 5418 from 5892 leaves us with 474.
Bring next digit (1) of the dividend behind the 474 and repeat the process: 4741 / 903

Going ahead to step 7:
If we divide 4741 by 903, we get 5 and a remainder of 226.
Use 5 as the next digit of our solution. 
Result so far: 6365.0
Subtracting 4515 from 4741 leaves us with 226.
Take the next digit (5) from the dividend and append it to 226, then repeat: 2265 / 903

Going ahead to step 8:
If we divide 2265 by 903, we get 2 and a remainder of 459.
The next digit of our result is 2. 
Result so far: 63652.0
Subtract 1806 from 2265 to get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 9:
903 can be fit into 4590 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 63652.5
Subtract 4515 from 4590 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
The number 903 fits into 750 0 times, leaving a remainder of 750.
The number 0 becomes the next digit in our result. 
Result so far: 63652.5
Subtract 0 from 750 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
903 goes into 7500 8 times with a remainder of 276.
Record the quotient 8 as the next digit in the result. 
Result so far: 63652.508
If we subtract 7224 from 7500, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 12:
2760 divided by 903 is 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 63652.5083
If we take 2709 away from 2760, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 13:
510 divided by 903 is 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 63652.5083
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 14:
When dividing 5100 by 903, we get 5 with a remainder of 585.
The next digit of our result is 5. 
Result so far: 63652.508305
The remainder is 585 after subtracting 4515 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Moving on to step 15:
When dividing 5850 by 903, we get 6 with a remainder of 432.
The number 6 becomes the next digit in our result. 
Result so far: 63652.5083056
If we take 5418 away from 5850, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 16:
903 can be fit into 4320 4 times, resulting in a remainder of 708.
Use 4 as the next digit of our solution. 
Result so far: 63652.50830564
Deduct 3612 from 4320 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

In conclusion, the division gives 63652.50830564 with a balance of 7.08e-07.
