We divide 81455123 by 801
We want to figure out the number of times 81455123 can be divided by 801.

Step 1:
801 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 801

On to step 2:
801 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 801

Moving on to step 3:
801 goes into 814 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 801 from 814 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 801

On to step 4:
801 can be fit into 135 0 times, resulting in a remainder of 135.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 135 and we're left with 135.
Fetch the next digit (5) from the dividend, attach it to 135 and continue: 1355 / 801

Step 5:
The number 801 fits into 1355 1 times, leaving a remainder of 554.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 801 from 1355 leaves us with 554.
Bring next digit (1) of the dividend behind the 554 and repeat the process: 5541 / 801

Moving on to step 6:
801 can be fit into 5541 6 times, resulting in a remainder of 735.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
If we take 4806 away from 5541, we end up with 735.
Grab the next digit (2) from the dividend, add it to 735, then carry on: 7352 / 801

Step 7:
801 goes into 7352 9 times with a remainder of 143.
Use 9 as the next digit of our solution. 
Result so far: 10169.0
Subtracting 7209 from 7352 leaves us with 143.
Take the next digit (3) from the dividend and append it to 143, then repeat: 1433 / 801

Moving on to step 8:
When dividing 1433 by 801, we get 1 with a remainder of 632.
Put 1 as the next digit of the answer. 
Result so far: 101691.0
Subtracting 801 from 1433 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 9:
801 goes into 6320 7 times with a remainder of 713.
Write down 7 as next digit of the result. 
Result so far: 101691.7
Deduct 5607 from 6320 and we're left with 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Going ahead to step 10:
801 goes into 7130 8 times with a remainder of 722.
Record the quotient 8 as the next digit in the result. 
Result so far: 101691.78
Subtract 6408 from 7130 to get 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Step 11:
801 goes into 7220 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 101691.789
If we take 7209 away from 7220, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
The number 801 fits into 110 0 times, leaving a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 101691.789
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
When dividing 1100 by 801, we get 1 with a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 101691.78901
Subtracting 801 from 1100 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 14:
2990 divided by 801 is 3 with a remainder of 587.
The next digit of our result is 3. 
Result so far: 101691.789013
If we subtract 2403 from 2990, we get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 15:
801 can be fit into 5870 7 times, resulting in a remainder of 263.
Put 7 as the next digit of the answer. 
Result so far: 101691.7890137
If we subtract 5607 from 5870, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 16:
2630 divided by 801 is 3 with a remainder of 227.
Use 3 as the next digit of our solution. 
Result so far: 101691.78901373
If we take 2403 away from 2630, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

In conclusion, the division gives 101691.78901373 with a balance of 2.27e-07.
