Let's divide 19115031 by 801
We're looking to find how many times 801 goes into 19115031.

On to step 1:
801 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 801

Moving on to step 2:
801 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 801

On to step 3:
If we divide 191 by 801, we get 0 and a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 191 leaves us with 191.
Fetch the next digit (1) from the dividend, attach it to 191 and continue: 1911 / 801

Advancing to step 4:
801 can be fit into 1911 2 times, resulting in a remainder of 309.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1602 away from 1911, we end up with 309.
Fetch the next digit (5) from the dividend, attach it to 309 and continue: 3095 / 801

On to step 5:
801 goes into 3095 3 times with a remainder of 692.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 2403 from 3095 to get 692.
Fetch the next digit (0) from the dividend, attach it to 692 and continue: 6920 / 801

Moving on to step 6:
When dividing 6920 by 801, we get 8 with a remainder of 512.
The next digit of our result is 8. 
Result so far: 238.0
If we subtract 6408 from 6920, we get 512.
Fetch the next digit (3) from the dividend, attach it to 512 and continue: 5123 / 801

Let's proceed to step 7:
The number 801 fits into 5123 6 times, leaving a remainder of 317.
Use 6 as the next digit of our solution. 
Result so far: 2386.0
If we take 4806 away from 5123, we end up with 317.
Grab the next digit (1) from the dividend, add it to 317, then carry on: 3171 / 801

Let's proceed to step 8:
When dividing 3171 by 801, we get 3 with a remainder of 768.
Write down 3 as next digit of the result. 
Result so far: 23863.0
If we subtract 2403 from 3171, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 9:
801 can be fit into 7680 9 times, resulting in a remainder of 471.
Put 9 as the next digit of the answer. 
Result so far: 23863.9
Deduct 7209 from 7680 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Advancing to step 10:
4710 divided by 801 is 5 with a remainder of 705.
Write down 5 as next digit of the result. 
Result so far: 23863.95
If we take 4005 away from 4710, we end up with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Advancing to step 11:
The number 801 fits into 7050 8 times, leaving a remainder of 642.
The number 8 becomes the next digit in our result. 
Result so far: 23863.958
If we take 6408 away from 7050, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 12:
6420 divided by 801 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 23863.9588
If we subtract 6408 from 6420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 23863.9588, and the remainder is 0.00012.
