54918512 divided by 403 
We're looking to find how many times 403 goes into 54918512.

Advancing to step 1:
The number 403 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 403

Step 2:
When dividing 54 by 403, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 403

On to step 3:
The number 403 fits into 549 1 times, leaving a remainder of 146.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 403 from 549, we get 146.
Fetch the next digit (1) from the dividend, attach it to 146 and continue: 1461 / 403

Moving on to step 4:
1461 divided by 403 is 3 with a remainder of 252.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1209 from 1461, we get 252.
Append the next digit (8) from the dividend to 252 and continue with: 2528 / 403

Advancing to step 5:
403 can be fit into 2528 6 times, resulting in a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
The remainder is 110 after subtracting 2418 from 2528.
Include the next digit (5) from the dividend after 110, then repeat: 1105 / 403

Step 6:
The number 403 fits into 1105 2 times, leaving a remainder of 299.
The next digit of our result is 2. 
Result so far: 1362.0
Deduct 806 from 1105 and we're left with 299.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 403

Let's proceed to step 7:
403 goes into 2991 7 times with a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 13627.0
Deduct 2821 from 2991 and we're left with 170.
Fetch the next digit (2) from the dividend, attach it to 170 and continue: 1702 / 403

On to step 8:
1702 divided by 403 is 4 with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 136274.0
Subtract 1612 from 1702 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
900 divided by 403 is 2 with a remainder of 94.
The next digit of our result is 2. 
Result so far: 136274.2
The remainder is 94 after subtracting 806 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
940 divided by 403 is 2 with a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 136274.22
If we subtract 806 from 940, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 136274.22 and a remainder of 0.134.
