Let's divide 53521778 by 903
We want to divide 53521778 by 903.

Advancing to step 1:
903 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 903

Let's proceed to step 2:
When dividing 53 by 903, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 903

Going ahead to step 3:
The number 903 fits into 535 0 times, leaving a remainder of 535.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 535 after subtracting 0 from 535.
Take the next digit (2) from the dividend and append it to 535, then repeat: 5352 / 903

Step 4:
903 can be fit into 5352 5 times, resulting in a remainder of 837.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4515 away from 5352, we end up with 837.
Take the next digit (1) from the dividend and append it to 837, then repeat: 8371 / 903

On to step 5:
If we divide 8371 by 903, we get 9 and a remainder of 244.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 8127 from 8371, we get 244.
Take the next digit (7) from the dividend and append it to 244, then repeat: 2447 / 903

Moving on to step 6:
903 goes into 2447 2 times with a remainder of 641.
Put 2 as the next digit of the answer. 
Result so far: 592.0
If we take 1806 away from 2447, we end up with 641.
Include the next digit (7) from the dividend after 641, then repeat: 6417 / 903

Step 7:
If we divide 6417 by 903, we get 7 and a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 5927.0
If we subtract 6321 from 6417, we get 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 903

Step 8:
When dividing 968 by 903, we get 1 with a remainder of 65.
The next digit of our result is 1. 
Result so far: 59271.0
Subtract 903 from 968 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
The number 903 fits into 650 0 times, leaving a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 59271.0
Subtract 0 from 650 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 10:
The number 903 fits into 6500 7 times, leaving a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 59271.07
Subtract 6321 from 6500 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 11:
When dividing 1790 by 903, we get 1 with a remainder of 887.
Put 1 as the next digit of the answer. 
Result so far: 59271.071
If we subtract 903 from 1790, we get 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

Moving on to step 12:
If we divide 8870 by 903, we get 9 and a remainder of 743.
The number 9 becomes the next digit in our result. 
Result so far: 59271.0719
The remainder is 743 after subtracting 8127 from 8870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Going ahead to step 13:
903 goes into 7430 8 times with a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 59271.07198
The remainder is 206 after subtracting 7224 from 7430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 14:
903 can be fit into 2060 2 times, resulting in a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 59271.071982
Deduct 1806 from 2060 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 15:
The number 903 fits into 2540 2 times, leaving a remainder of 734.
Write down 2 as next digit of the result. 
Result so far: 59271.0719822
Deduct 1806 from 2540 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

The final result is 59271.0719822 with a remainder of 7.34e-06.
