Let's divide 15103346 by 801
We want to figure out the number of times 15103346 can be divided by 801.

Going ahead to step 1:
801 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 801

Let's proceed to step 2:
15 divided by 801 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 801

Let's proceed to step 3:
When dividing 151 by 801, we get 0 with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Bring next digit (0) of the dividend behind the 151 and repeat the process: 1510 / 801

Going ahead to step 4:
If we divide 1510 by 801, we get 1 and a remainder of 709.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 801 away from 1510, we end up with 709.
Fetch the next digit (3) from the dividend, attach it to 709 and continue: 7093 / 801

Moving on to step 5:
801 can be fit into 7093 8 times, resulting in a remainder of 685.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 6408 from 7093 leaves us with 685.
Grab the next digit (3) from the dividend, add it to 685, then carry on: 6853 / 801

Let's proceed to step 6:
801 can be fit into 6853 8 times, resulting in a remainder of 445.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtracting 6408 from 6853 leaves us with 445.
Append the next digit (4) from the dividend to 445 and continue with: 4454 / 801

On to step 7:
The number 801 fits into 4454 5 times, leaving a remainder of 449.
Use 5 as the next digit of our solution. 
Result so far: 1885.0
The remainder is 449 after subtracting 4005 from 4454.
Take the next digit (6) from the dividend and append it to 449, then repeat: 4496 / 801

Moving on to step 8:
If we divide 4496 by 801, we get 5 and a remainder of 491.
Record the quotient 5 as the next digit in the result. 
Result so far: 18855.0
Subtracting 4005 from 4496 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 9:
801 goes into 4910 6 times with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 18855.6
Subtract 4806 from 4910 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
801 can be fit into 1040 1 times, resulting in a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 18855.61
Subtracting 801 from 1040 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 11:
2390 divided by 801 is 2 with a remainder of 788.
Write down 2 as next digit of the result. 
Result so far: 18855.612
If we subtract 1602 from 2390, we get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Advancing to step 12:
7880 divided by 801 is 9 with a remainder of 671.
The number 9 becomes the next digit in our result. 
Result so far: 18855.6129
Deduct 7209 from 7880 and we're left with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Step 13:
801 can be fit into 6710 8 times, resulting in a remainder of 302.
Write down 8 as next digit of the result. 
Result so far: 18855.61298
Deduct 6408 from 6710 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 14:
If we divide 3020 by 801, we get 3 and a remainder of 617.
Use 3 as the next digit of our solution. 
Result so far: 18855.612983
Subtract 2403 from 3020 to get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Moving on to step 15:
801 can be fit into 6170 7 times, resulting in a remainder of 563.
Write down 7 as next digit of the result. 
Result so far: 18855.6129837
Subtracting 5607 from 6170 leaves us with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 16:
801 can be fit into 5630 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 18855.61298377
Deduct 5607 from 5630 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 18855.61298377, and the remainder is 2.3e-08.
