21226971 divided by 801 
We want to divide 21226971 by 801.

Advancing to step 1:
801 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 801

On to step 2:
When dividing 21 by 801, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 801

Step 3:
The number 801 fits into 212 0 times, leaving a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Grab the next digit (2) from the dividend, add it to 212, then carry on: 2122 / 801

Moving on to step 4:
2122 divided by 801 is 2 with a remainder of 520.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1602 from 2122 leaves us with 520.
Fetch the next digit (6) from the dividend, attach it to 520 and continue: 5206 / 801

Step 5:
When dividing 5206 by 801, we get 6 with a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 4806 from 5206, we get 400.
Fetch the next digit (9) from the dividend, attach it to 400 and continue: 4009 / 801

Moving on to step 6:
The number 801 fits into 4009 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 265.0
Subtracting 4005 from 4009 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 801

Advancing to step 7:
47 divided by 801 is 0 with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 2650.0
If we subtract 0 from 47, we get 47.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 801

Advancing to step 8:
471 divided by 801 is 0 with a remainder of 471.
Record the quotient 0 as the next digit in the result. 
Result so far: 26500.0
Deduct 0 from 471 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.

Let's proceed to step 9:
When dividing 4710 by 801, we get 5 with a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 26500.5
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.

On to step 10:
The number 801 fits into 7050 8 times, leaving a remainder of 642.
Write down 8 as next digit of the result. 
Result so far: 26500.58
If we subtract 6408 from 7050, we get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Step 11:
The number 801 fits into 6420 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 26500.588
Subtracting 6408 from 6420 leaves us with 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 final result is 26500.588 with a remainder of 0.0012.
