5 divided by 411 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 411

Advancing to step 2:
411 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 411

Advancing to step 3:
The number 411 fits into 513 1 times, leaving a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 411 away from 513, we end up with 102.
Take the next digit (6) from the dividend and append it to 102, then repeat: 1026 / 411

On to step 4:
411 goes into 1026 2 times with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 822 from 1026, we get 204.
Fetch the next digit (5) from the dividend, attach it to 204 and continue: 2045 / 411

On to step 5:
If we divide 2045 by 411, we get 4 and a remainder of 401.
The next digit of our result is 4. 
Result so far: 124.0
If we subtract 1644 from 2045, we get 401.
Append the next digit (3) from the dividend to 401 and continue with: 4013 / 411

Advancing to step 6:
When dividing 4013 by 411, we get 9 with a remainder of 314.
Use 9 as the next digit of our solution. 
Result so far: 1249.0
The remainder is 314 after subtracting 3699 from 4013.
Fetch the next digit (0) from the dividend, attach it to 314 and continue: 3140 / 411

On to step 7:
411 can be fit into 3140 7 times, resulting in a remainder of 263.
The next digit of our result is 7. 
Result so far: 12497.0
If we take 2877 away from 3140, we end up with 263.
Bring next digit (3) of the dividend behind the 263 and repeat the process: 2633 / 411

Step 8:
411 goes into 2633 6 times with a remainder of 167.
The number 6 becomes the next digit in our result. 
Result so far: 124976.0
The remainder is 167 after subtracting 2466 from 2633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 9:
The number 411 fits into 1670 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 124976.4
Deduct 1644 from 1670 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 411 fits into 260 0 times, leaving a remainder of 260.
The next digit of our result is 0. 
Result so far: 124976.4
Subtract 0 from 260 to get 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:
2600 divided by 411 is 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 124976.406
Deduct 2466 from 2600 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 12:
411 goes into 1340 3 times with a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 124976.4063
If we subtract 1233 from 1340, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 13:
1070 divided by 411 is 2 with a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 124976.40632
Deduct 822 from 1070 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 14:
The number 411 fits into 2480 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 124976.406326
Subtract 2466 from 2480 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
When dividing 140 by 411, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 124976.406326
If we take 0 away from 140, we end up 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.

Going ahead to step 16:
When dividing 1400 by 411, we get 3 with a remainder of 167.
The next digit of our result is 3. 
Result so far: 124976.40632603
Deduct 1233 from 1400 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

In conclusion, the division gives 124976.40632603 with a balance of 1.67e-07.
