We're dividing 81221574 by 406 
We want to figure out the number of times 81221574 can be divided by 406.

Advancing to step 1:
8 divided by 406 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 406

Step 2:
When dividing 81 by 406, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 406

Step 3:
812 divided by 406 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 812 from 812.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 406

Moving on to step 4:
The number 406 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 406

Let's proceed to step 5:
When dividing 21 by 406, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 406

Advancing to step 6:
406 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 2000.0
Subtracting 0 from 215 leaves us with 215.
Grab the next digit (7) from the dividend, add it to 215, then carry on: 2157 / 406

Going ahead to step 7:
When dividing 2157 by 406, we get 5 with a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 20005.0
Deduct 2030 from 2157 and we're left with 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 406

Step 8:
The number 406 fits into 1274 3 times, leaving a remainder of 56.
The next digit of our result is 3. 
Result so far: 200053.0
The remainder is 56 after subtracting 1218 from 1274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 406 is 1 with a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 200053.1
If we take 406 away from 560, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
When dividing 1540 by 406, we get 3 with a remainder of 322.
Put 3 as the next digit of the answer. 
Result so far: 200053.13
The remainder is 322 after subtracting 1218 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 11:
When dividing 3220 by 406, we get 7 with a remainder of 378.
Use 7 as the next digit of our solution. 
Result so far: 200053.137
If we subtract 2842 from 3220, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 12:
If we divide 3780 by 406, we get 9 and a remainder of 126.
Put 9 as the next digit of the answer. 
Result so far: 200053.1379
If we take 3654 away from 3780, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 13:
1260 divided by 406 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 200053.13793
Deduct 1218 from 1260 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
420 divided by 406 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 200053.137931
If we take 406 away from 420, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 15:
406 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 200053.137931
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
The number 406 fits into 1400 3 times, leaving a remainder of 182.
Put 3 as the next digit of the answer. 
Result so far: 200053.13793103
If we take 1218 away from 1400, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

In conclusion, the division gives 200053.13793103 with a balance of 1.82e-07.
