81298421 ÷ 22 
Let's see how many times 22 fits into 81298421.

Going ahead to step 1:
If we divide 8 by 22, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 22

On to step 2:
If we divide 81 by 22, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 66 from 81 leaves us with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 22

Let's proceed to step 3:
If we divide 152 by 22, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtracting 132 from 152 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 22

Going ahead to step 4:
22 can be fit into 209 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 369.0
Subtract 198 from 209 to get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 22

Step 5:
If we divide 118 by 22, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 3695.0
If we take 110 away from 118, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 22

Advancing to step 6:
When dividing 84 by 22, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 36953.0
Subtract 66 from 84 to get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 22

Step 7:
The number 22 fits into 182 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 369538.0
Subtract 176 from 182 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 22

Going ahead to step 8:
61 divided by 22 is 2 with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 3695382.0
The remainder is 17 after subtracting 44 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 22 is 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 3695382.7
If we take 154 away from 170, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
22 goes into 160 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 3695382.77
Subtracting 154 from 160 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 3695382.77 with a remaining 0.006.
