21966122 divided by 8 
Our goal is to divide 21966122 by 8.

Step 1:
The number 8 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 8

Step 2:
When dividing 21 by 8, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 16 from 21 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 8

Advancing to step 3:
59 divided by 8 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 56 from 59 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 8

Moving on to step 4:
When dividing 36 by 8, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
If we take 32 away from 36, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 8

Let's proceed to step 5:
When dividing 46 by 8, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 2745.0
If we subtract 40 from 46, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 8

Going ahead to step 6:
When dividing 61 by 8, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 27457.0
Subtract 56 from 61 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 8

Advancing to step 7:
When dividing 52 by 8, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 274576.0
If we subtract 48 from 52, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 8

Let's proceed to step 8:
8 can be fit into 42 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 2745765.0
Deduct 40 from 42 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
When dividing 20 by 8, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2745765.2
If we take 16 away from 20, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2745765.25
Subtract 40 from 40 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2745765.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2745765.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2745765.25, and the remainder is 0.0.
