We're dividing 15610538 by 801 
We want to divide 15610538 by 801.

Moving on to step 1:
1 divided by 801 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 801

Going ahead to step 2:
The number 801 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 801

On to step 3:
The number 801 fits into 156 0 times, leaving a remainder of 156.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Grab the next digit (1) from the dividend, add it to 156, then carry on: 1561 / 801

On to step 4:
1561 divided by 801 is 1 with a remainder of 760.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 801 from 1561, we get 760.
Fetch the next digit (0) from the dividend, attach it to 760 and continue: 7600 / 801

Going ahead to step 5:
The number 801 fits into 7600 9 times, leaving a remainder of 391.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 7209 from 7600, we get 391.
Include the next digit (5) from the dividend after 391, then repeat: 3915 / 801

On to step 6:
801 goes into 3915 4 times with a remainder of 711.
Write down 4 as next digit of the result. 
Result so far: 194.0
If we take 3204 away from 3915, we end up with 711.
Include the next digit (3) from the dividend after 711, then repeat: 7113 / 801

Moving on to step 7:
801 goes into 7113 8 times with a remainder of 705.
Record the quotient 8 as the next digit in the result. 
Result so far: 1948.0
The remainder is 705 after subtracting 6408 from 7113.
Bring next digit (8) of the dividend behind the 705 and repeat the process: 7058 / 801

Let's proceed to step 8:
7058 divided by 801 is 8 with a remainder of 650.
Record the quotient 8 as the next digit in the result. 
Result so far: 19488.0
Subtract 6408 from 7058 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 9:
801 can be fit into 6500 8 times, resulting in a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 19488.8
Subtract 6408 from 6500 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
801 goes into 920 1 times with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 19488.81
The remainder is 119 after subtracting 801 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 11:
The number 801 fits into 1190 1 times, leaving a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 19488.811
Subtracting 801 from 1190 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

The quotient of the division is 19488.811, and the remainder is 0.0389.
