We divide 870638 by 22
Let's see how many times 22 fits into 870638.

Advancing to step 1:
If we divide 8 by 22, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 22

Advancing to step 2:
22 goes into 87 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 66 from 87 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 22

Going ahead to step 3:
210 divided by 22 is 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 198 from 210, we get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 22

Step 4:
126 divided by 22 is 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 395.0
The remainder is 16 after subtracting 110 from 126.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 22

Going ahead to step 5:
The number 22 fits into 163 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3957.0
Subtracting 154 from 163 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 22

Moving on to step 6:
22 goes into 98 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 39574.0
The remainder is 10 after subtracting 88 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 22 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 39574.4
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
The number 22 fits into 120 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 39574.45
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
22 goes into 100 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 39574.454
Subtract 88 from 100 to get 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 10:
When dividing 120 by 22, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 39574.4545
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
22 can be fit into 100 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 39574.45454
Deduct 88 from 100 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.

Moving on to step 12:
120 divided by 22 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 39574.454545
Subtract 110 from 120 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
22 can be fit into 100 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 39574.4545454
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
22 can be fit into 120 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 39574.45454545
Subtract 110 from 120 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 39574.45454545 with a remainder of 1e-08.
