22616445 ÷ 21 
Our goal is to divide 22616445 by 21.

Going ahead to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 21

Going ahead to step 2:
If we divide 22 by 21, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 22 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 21

Step 3:
21 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 21

On to step 4:
The number 21 fits into 161 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 147 away from 161, we end up with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 21

Advancing to step 5:
21 can be fit into 146 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1076.0
Deduct 126 from 146 and we're left with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 21

Going ahead to step 6:
21 can be fit into 204 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 10769.0
Subtract 189 from 204 to get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 21

On to step 7:
When dividing 154 by 21, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 107697.0
Subtract 147 from 154 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 21

Step 8:
75 divided by 21 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1076973.0
If we take 63 away from 75, we end up 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.

Going ahead to step 9:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1076973.5
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 21 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1076973.57
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1076973.571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
21 goes into 90 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1076973.5714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 1076973.57142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 1076973.571428
Deduct 168 from 180 and we're left 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.

Advancing to step 15:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1076973.5714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 16:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1076973.57142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 1076973.57142857 with a remaining 3e-09.
