53213431 divided by 418 
Let's see how many times 418 fits into 53213431.

Step 1:
If we divide 5 by 418, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 418

Advancing to step 2:
53 divided by 418 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 418

Let's proceed to step 3:
When dividing 532 by 418, we get 1 with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 418 from 532 leaves us with 114.
Grab the next digit (1) from the dividend, add it to 114, then carry on: 1141 / 418

Moving on to step 4:
418 can be fit into 1141 2 times, resulting in a remainder of 305.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 305 after subtracting 836 from 1141.
Fetch the next digit (3) from the dividend, attach it to 305 and continue: 3053 / 418

On to step 5:
The number 418 fits into 3053 7 times, leaving a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 2926 from 3053, we get 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 418

Moving on to step 6:
418 goes into 1274 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1273.0
Subtracting 1254 from 1274 leaves us with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 418

Moving on to step 7:
When dividing 203 by 418, we get 0 with a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 12730.0
If we take 0 away from 203, we end up with 203.
Fetch the next digit (1) from the dividend, attach it to 203 and continue: 2031 / 418

Step 8:
418 can be fit into 2031 4 times, resulting in a remainder of 359.
The number 4 becomes the next digit in our result. 
Result so far: 127304.0
Subtract 1672 from 2031 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 9:
418 can be fit into 3590 8 times, resulting in a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 127304.8
The remainder is 246 after subtracting 3344 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 10:
418 can be fit into 2460 5 times, resulting in a remainder of 370.
The next digit of our result is 5. 
Result so far: 127304.85
Subtracting 2090 from 2460 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 11:
3700 divided by 418 is 8 with a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 127304.858
Subtracting 3344 from 3700 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 12:
When dividing 3560 by 418, we get 8 with a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 127304.8588
If we subtract 3344 from 3560, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 127304.8588 and a remainder of 0.00216.
