81925821 divided by 105 
We're looking to find how many times 105 goes into 81925821.

Step 1:
105 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 105

Going ahead to step 2:
When dividing 81 by 105, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 105

Advancing to step 3:
105 can be fit into 819 7 times, resulting in a remainder of 84.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 735 from 819 and we're left with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 105

On to step 4:
If we divide 842 by 105, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 2 after subtracting 840 from 842.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 105

On to step 5:
105 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
If we take 0 away from 25, we end up with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 105

Let's proceed to step 6:
When dividing 258 by 105, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 7802.0
Subtract 210 from 258 to get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 105

On to step 7:
105 goes into 482 4 times with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 78024.0
If we take 420 away from 482, we end up with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 105

Advancing to step 8:
The number 105 fits into 621 5 times, leaving a remainder of 96.
Put 5 as the next digit of the answer. 
Result so far: 780245.0
Deduct 525 from 621 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
If we divide 960 by 105, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 780245.9
Subtract 945 from 960 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 105, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 780245.91
Deduct 105 from 150 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
450 divided by 105 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 780245.914
Deduct 420 from 450 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 105 is 2 with a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 780245.9142
The remainder is 90 after subtracting 210 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
When dividing 900 by 105, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 780245.91428
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
When dividing 600 by 105, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 780245.914285
If we take 525 away from 600, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
105 goes into 750 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 780245.9142857
Subtract 735 from 750 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
105 goes into 150 1 times with a remainder of 45.
The next digit of our result is 1. 
Result so far: 780245.91428571
The remainder is 45 after subtracting 105 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 780245.91428571 with a balance of 4.5e-08.
