81212272 divided by 381 
We want to figure out the number of times 81212272 can be divided by 381.

On to step 1:
381 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 381

Moving on to step 2:
When dividing 81 by 381, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 381

Step 3:
812 divided by 381 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 762 from 812, we get 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 381

Step 4:
381 goes into 501 1 times with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 381 from 501 to get 120.
Fetch the next digit (2) from the dividend, attach it to 120 and continue: 1202 / 381

Advancing to step 5:
1202 divided by 381 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtracting 1143 from 1202 leaves us with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 381

Moving on to step 6:
381 can be fit into 592 1 times, resulting in a remainder of 211.
The next digit of our result is 1. 
Result so far: 2131.0
If we take 381 away from 592, we end up with 211.
Fetch the next digit (7) from the dividend, attach it to 211 and continue: 2117 / 381

Advancing to step 7:
The number 381 fits into 2117 5 times, leaving a remainder of 212.
Record the quotient 5 as the next digit in the result. 
Result so far: 21315.0
Deduct 1905 from 2117 and we're left with 212.
Bring next digit (2) of the dividend behind the 212 and repeat the process: 2122 / 381

Going ahead to step 8:
When dividing 2122 by 381, we get 5 with a remainder of 217.
Use 5 as the next digit of our solution. 
Result so far: 213155.0
If we subtract 1905 from 2122, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 9:
2170 divided by 381 is 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 213155.5
Deduct 1905 from 2170 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
When dividing 2650 by 381, we get 6 with a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 213155.56
Subtracting 2286 from 2650 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 11:
When dividing 3640 by 381, we get 9 with a remainder of 211.
The number 9 becomes the next digit in our result. 
Result so far: 213155.569
Deduct 3429 from 3640 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 12:
381 goes into 2110 5 times with a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 213155.5695
Subtract 1905 from 2110 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 13:
381 goes into 2050 5 times with a remainder of 145.
The next digit of our result is 5. 
Result so far: 213155.56955
If we subtract 1905 from 2050, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 213155.56955 with a remainder of 0.000145.
