81521583 divided by 383 
We want to figure out the number of times 81521583 can be divided by 383.

Going ahead to step 1:
8 divided by 383 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 383

Step 2:
When dividing 81 by 383, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 383

Going ahead to step 3:
383 can be fit into 815 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 49 after subtracting 766 from 815.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 383

Going ahead to step 4:
383 goes into 492 1 times with a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 383 from 492 to get 109.
Append the next digit (1) from the dividend to 109 and continue with: 1091 / 383

Step 5:
1091 divided by 383 is 2 with a remainder of 325.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 766 from 1091 leaves us with 325.
Include the next digit (5) from the dividend after 325, then repeat: 3255 / 383

Advancing to step 6:
The number 383 fits into 3255 8 times, leaving a remainder of 191.
The next digit of our result is 8. 
Result so far: 2128.0
Deduct 3064 from 3255 and we're left with 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 383

Let's proceed to step 7:
383 goes into 1918 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 21285.0
If we take 1915 away from 1918, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 383

On to step 8:
When dividing 33 by 383, we get 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 212850.0
Subtract 0 from 33 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 383, we get 0 with a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 212850.0
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
The number 383 fits into 3300 8 times, leaving a remainder of 236.
Use 8 as the next digit of our solution. 
Result so far: 212850.08
The remainder is 236 after subtracting 3064 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 11:
If we divide 2360 by 383, we get 6 and a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 212850.086
Deduct 2298 from 2360 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
383 can be fit into 620 1 times, resulting in a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 212850.0861
If we subtract 383 from 620, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 13:
383 can be fit into 2370 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 212850.08616
Subtracting 2298 from 2370 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
If we divide 720 by 383, we get 1 and a remainder of 337.
Record the quotient 1 as the next digit in the result. 
Result so far: 212850.086161
Deduct 383 from 720 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 15:
When dividing 3370 by 383, we get 8 with a remainder of 306.
Write down 8 as next digit of the result. 
Result so far: 212850.0861618
Subtract 3064 from 3370 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 16:
383 can be fit into 3060 7 times, resulting in a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 212850.08616187
The remainder is 379 after subtracting 2681 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

The final outcome is 212850.08616187, with a leftover of 3.79e-07.
