We're dividing 54956408 by 412 
We want to divide 54956408 by 412.

Moving on to step 1:
412 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 412

Step 2:
If we divide 54 by 412, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 412

Moving on to step 3:
412 goes into 549 1 times with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 412 from 549 to get 137.
Include the next digit (5) from the dividend after 137, then repeat: 1375 / 412

Step 4:
412 can be fit into 1375 3 times, resulting in a remainder of 139.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1236 from 1375 leaves us with 139.
Append the next digit (6) from the dividend to 139 and continue with: 1396 / 412

Going ahead to step 5:
412 can be fit into 1396 3 times, resulting in a remainder of 160.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 1236 from 1396 to get 160.
Bring next digit (4) of the dividend behind the 160 and repeat the process: 1604 / 412

On to step 6:
412 goes into 1604 3 times with a remainder of 368.
The next digit of our result is 3. 
Result so far: 1333.0
If we take 1236 away from 1604, we end up with 368.
Grab the next digit (0) from the dividend, add it to 368, then carry on: 3680 / 412

On to step 7:
3680 divided by 412 is 8 with a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 13338.0
Deduct 3296 from 3680 and we're left with 384.
Take the next digit (8) from the dividend and append it to 384, then repeat: 3848 / 412

Moving on to step 8:
The number 412 fits into 3848 9 times, leaving a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 133389.0
Deduct 3708 from 3848 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
1400 divided by 412 is 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 133389.3
If we subtract 1236 from 1400, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 10:
When dividing 1640 by 412, we get 3 with a remainder of 404.
The next digit of our result is 3. 
Result so far: 133389.33
Subtract 1236 from 1640 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final outcome is 133389.33, with a leftover of 0.404.
