We're dividing 2191451 by 406 
We want to figure out the number of times 2191451 can be divided by 406.

Advancing to step 1:
406 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 406

On to step 2:
If we divide 21 by 406, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 406

Advancing to step 3:
The number 406 fits into 219 0 times, leaving a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Append the next digit (1) from the dividend to 219 and continue with: 2191 / 406

Going ahead to step 4:
When dividing 2191 by 406, we get 5 with a remainder of 161.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 2030 from 2191 leaves us with 161.
Take the next digit (4) from the dividend and append it to 161, then repeat: 1614 / 406

Going ahead to step 5:
If we divide 1614 by 406, we get 3 and a remainder of 396.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 1218 from 1614, we get 396.
Include the next digit (5) from the dividend after 396, then repeat: 3965 / 406

Let's proceed to step 6:
If we divide 3965 by 406, we get 9 and a remainder of 311.
The number 9 becomes the next digit in our result. 
Result so far: 539.0
If we take 3654 away from 3965, we end up with 311.
Include the next digit (1) from the dividend after 311, then repeat: 3111 / 406

On to step 7:
406 can be fit into 3111 7 times, resulting in a remainder of 269.
The number 7 becomes the next digit in our result. 
Result so far: 5397.0
Subtract 2842 from 3111 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 8:
The number 406 fits into 2690 6 times, leaving a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 5397.6
Subtract 2436 from 2690 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 9:
406 goes into 2540 6 times with a remainder of 104.
The next digit of our result is 6. 
Result so far: 5397.66
The remainder is 104 after subtracting 2436 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 5397.66, with a leftover of 0.104.
