We divide 53993424 by 408
We want to figure out the number of times 53993424 can be divided by 408.

Advancing to step 1:
408 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 408

Advancing to step 2:
The number 408 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 408

Step 3:
The number 408 fits into 539 1 times, leaving a remainder of 131.
The next digit of our result is 1. 
Result so far: 1.0
If we take 408 away from 539, we end up with 131.
Include the next digit (9) from the dividend after 131, then repeat: 1319 / 408

Let's proceed to step 4:
When dividing 1319 by 408, we get 3 with a remainder of 95.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1224 from 1319, we get 95.
Fetch the next digit (3) from the dividend, attach it to 95 and continue: 953 / 408

Going ahead to step 5:
When dividing 953 by 408, we get 2 with a remainder of 137.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
The remainder is 137 after subtracting 816 from 953.
Grab the next digit (4) from the dividend, add it to 137, then carry on: 1374 / 408

Advancing to step 6:
The number 408 fits into 1374 3 times, leaving a remainder of 150.
Use 3 as the next digit of our solution. 
Result so far: 1323.0
The remainder is 150 after subtracting 1224 from 1374.
Fetch the next digit (2) from the dividend, attach it to 150 and continue: 1502 / 408

Moving on to step 7:
If we divide 1502 by 408, we get 3 and a remainder of 278.
Put 3 as the next digit of the answer. 
Result so far: 13233.0
Deduct 1224 from 1502 and we're left with 278.
Fetch the next digit (4) from the dividend, attach it to 278 and continue: 2784 / 408

Going ahead to step 8:
When dividing 2784 by 408, we get 6 with a remainder of 336.
The next digit of our result is 6. 
Result so far: 132336.0
If we subtract 2448 from 2784, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 9:
If we divide 3360 by 408, we get 8 and a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 132336.8
Deduct 3264 from 3360 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
When dividing 960 by 408, we get 2 with a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 132336.82
The remainder is 144 after subtracting 816 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
If we divide 1440 by 408, we get 3 and a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 132336.823
If we subtract 1224 from 1440, 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.

Advancing to step 12:
408 can be fit into 2160 5 times, resulting in a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 132336.8235
The remainder is 120 after subtracting 2040 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
If we divide 1200 by 408, we get 2 and a remainder of 384.
The next digit of our result is 2. 
Result so far: 132336.82352
The remainder is 384 after subtracting 816 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 14:
The number 408 fits into 3840 9 times, leaving a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 132336.823529
Deduct 3672 from 3840 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 15:
When dividing 1680 by 408, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 132336.8235294
Deduct 1632 from 1680 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
The number 408 fits into 480 1 times, leaving a remainder of 72.
The next digit of our result is 1. 
Result so far: 132336.82352941
Deduct 408 from 480 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 132336.82352941 with a balance of 7.2e-08.
