13210020 ÷ 222 
We're looking to find how many times 222 goes into 13210020.

Step 1:
If we divide 1 by 222, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 222

On to step 2:
When dividing 13 by 222, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 222

Going ahead to step 3:
222 goes into 132 0 times with a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 222

Let's proceed to step 4:
222 goes into 1321 5 times with a remainder of 211.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 1110 from 1321 and we're left with 211.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 222

Let's proceed to step 5:
If we divide 2110 by 222, we get 9 and a remainder of 112.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtract 1998 from 2110 to get 112.
Append the next digit (0) from the dividend to 112 and continue with: 1120 / 222

Let's proceed to step 6:
222 goes into 1120 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 595.0
Deduct 1110 from 1120 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 222

Step 7:
222 goes into 102 0 times with a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 5950.0
Subtracting 0 from 102 leaves us with 102.
Include the next digit (0) from the dividend after 102, then repeat: 1020 / 222

Let's proceed to step 8:
1020 divided by 222 is 4 with a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 59504.0
The remainder is 132 after subtracting 888 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 9:
The number 222 fits into 1320 5 times, leaving a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 59504.5
If we take 1110 away from 1320, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
222 can be fit into 2100 9 times, resulting in a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 59504.59
The remainder is 102 after subtracting 1998 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 11:
The number 222 fits into 1020 4 times, leaving a remainder of 132.
The next digit of our result is 4. 
Result so far: 59504.594
Deduct 888 from 1020 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 12:
1320 divided by 222 is 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 59504.5945
Subtracting 1110 from 1320 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 13:
2100 divided by 222 is 9 with a remainder of 102.
The number 9 becomes the next digit in our result. 
Result so far: 59504.59459
If we subtract 1998 from 2100, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 14:
222 goes into 1020 4 times with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 59504.594594
If we take 888 away from 1020, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 15:
If we divide 1320 by 222, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 59504.5945945
If we subtract 1110 from 1320, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 16:
If we divide 2100 by 222, we get 9 and a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 59504.59459459
Subtract 1998 from 2100 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 59504.59459459 with a remainder of 1.02e-07.
