We divide 21619810 by 618
We want to figure out the number of times 21619810 can be divided by 618.

On to step 1:
If we divide 2 by 618, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 618

Step 2:
When dividing 21 by 618, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 618

Moving on to step 3:
When dividing 216 by 618, we get 0 with a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Bring next digit (1) of the dividend behind the 216 and repeat the process: 2161 / 618

On to step 4:
When dividing 2161 by 618, we get 3 with a remainder of 307.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1854 from 2161 leaves us with 307.
Include the next digit (9) from the dividend after 307, then repeat: 3079 / 618

Going ahead to step 5:
3079 divided by 618 is 4 with a remainder of 607.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 2472 from 3079 and we're left with 607.
Append the next digit (8) from the dividend to 607 and continue with: 6078 / 618

Let's proceed to step 6:
If we divide 6078 by 618, we get 9 and a remainder of 516.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
If we subtract 5562 from 6078, we get 516.
Bring next digit (1) of the dividend behind the 516 and repeat the process: 5161 / 618

On to step 7:
5161 divided by 618 is 8 with a remainder of 217.
The number 8 becomes the next digit in our result. 
Result so far: 3498.0
If we subtract 4944 from 5161, we get 217.
Bring next digit (0) of the dividend behind the 217 and repeat the process: 2170 / 618

Advancing to step 8:
618 can be fit into 2170 3 times, resulting in a remainder of 316.
The number 3 becomes the next digit in our result. 
Result so far: 34983.0
The remainder is 316 after subtracting 1854 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 9:
The number 618 fits into 3160 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 34983.5
If we subtract 3090 from 3160, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
When dividing 700 by 618, we get 1 with a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 34983.51
Deduct 618 from 700 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
618 goes into 820 1 times with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 34983.511
If we subtract 618 from 820, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

After the division, we end up with 34983.511 and a remainder of 0.0202.
