Let's divide 54486273 by 406
We want to divide 54486273 by 406.

Advancing to step 1:
5 divided by 406 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 406

Going ahead to step 2:
If we divide 54 by 406, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 406

Step 3:
406 can be fit into 544 1 times, resulting in a remainder of 138.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 406 from 544 to get 138.
Take the next digit (8) from the dividend and append it to 138, then repeat: 1388 / 406

Advancing to step 4:
When dividing 1388 by 406, we get 3 with a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1218 away from 1388, we end up with 170.
Bring next digit (6) of the dividend behind the 170 and repeat the process: 1706 / 406

Step 5:
406 can be fit into 1706 4 times, resulting in a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we subtract 1624 from 1706, we get 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 406

Let's proceed to step 6:
406 goes into 822 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 1342.0
Deduct 812 from 822 and we're left with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 406

Moving on to step 7:
406 can be fit into 107 0 times, resulting in a remainder of 107.
Record the quotient 0 as the next digit in the result. 
Result so far: 13420.0
If we take 0 away from 107, we end up with 107.
Take the next digit (3) from the dividend and append it to 107, then repeat: 1073 / 406

On to step 8:
If we divide 1073 by 406, we get 2 and a remainder of 261.
Put 2 as the next digit of the answer. 
Result so far: 134202.0
If we take 812 away from 1073, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 9:
When dividing 2610 by 406, we get 6 with a remainder of 174.
Record the quotient 6 as the next digit in the result. 
Result so far: 134202.6
If we subtract 2436 from 2610, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 10:
1740 divided by 406 is 4 with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 134202.64
Subtract 1624 from 1740 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 11:
406 can be fit into 1160 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 134202.642
Deduct 812 from 1160 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 12:
The number 406 fits into 3480 8 times, leaving a remainder of 232.
The next digit of our result is 8. 
Result so far: 134202.6428
Subtracting 3248 from 3480 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 13:
If we divide 2320 by 406, we get 5 and a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 134202.64285
Subtracting 2030 from 2320 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
2900 divided by 406 is 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 134202.642857
Subtracting 2842 from 2900 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
406 can be fit into 580 1 times, resulting in a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 134202.6428571
If we take 406 away from 580, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
If we divide 1740 by 406, we get 4 and a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 134202.64285714
Subtract 1624 from 1740 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Our division results in 134202.64285714 with a remaining 1.16e-07.
