We're dividing 55790249 by 408 
Our goal is to divide 55790249 by 408.

Moving on to step 1:
When dividing 5 by 408, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 408

Advancing to step 2:
408 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 408

Let's proceed to step 3:
When dividing 557 by 408, we get 1 with a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 408 from 557 leaves us with 149.
Bring next digit (9) of the dividend behind the 149 and repeat the process: 1499 / 408

Step 4:
The number 408 fits into 1499 3 times, leaving a remainder of 275.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1224 away from 1499, we end up with 275.
Bring next digit (0) of the dividend behind the 275 and repeat the process: 2750 / 408

On to step 5:
408 goes into 2750 6 times with a remainder of 302.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtracting 2448 from 2750 leaves us with 302.
Include the next digit (2) from the dividend after 302, then repeat: 3022 / 408

On to step 6:
If we divide 3022 by 408, we get 7 and a remainder of 166.
Record the quotient 7 as the next digit in the result. 
Result so far: 1367.0
If we subtract 2856 from 3022, we get 166.
Bring next digit (4) of the dividend behind the 166 and repeat the process: 1664 / 408

On to step 7:
When dividing 1664 by 408, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 13674.0
If we take 1632 away from 1664, we end up with 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 408

Let's proceed to step 8:
329 divided by 408 is 0 with a remainder of 329.
The number 0 becomes the next digit in our result. 
Result so far: 136740.0
If we take 0 away from 329, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 9:
408 can be fit into 3290 8 times, resulting in a remainder of 26.
The next digit of our result is 8. 
Result so far: 136740.8
Subtract 3264 from 3290 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
260 divided by 408 is 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 136740.8
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
408 goes into 2600 6 times with a remainder of 152.
The next digit of our result is 6. 
Result so far: 136740.806
If we take 2448 away from 2600, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
When dividing 1520 by 408, we get 3 with a remainder of 296.
The number 3 becomes the next digit in our result. 
Result so far: 136740.8063
If we subtract 1224 from 1520, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 13:
408 goes into 2960 7 times with a remainder of 104.
Write down 7 as next digit of the result. 
Result so far: 136740.80637
The remainder is 104 after subtracting 2856 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 14:
If we divide 1040 by 408, we get 2 and a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 136740.806372
If we subtract 816 from 1040, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 15:
2240 divided by 408 is 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 136740.8063725
Deduct 2040 from 2240 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 16:
If we divide 2000 by 408, we get 4 and a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 136740.80637254
Subtract 1632 from 2000 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 136740.80637254, with a leftover of 3.68e-07.
