21381819 ÷ 178 
We're looking to find how many times 178 goes into 21381819.

Moving on to step 1:
When dividing 2 by 178, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 178

Let's proceed to step 2:
178 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 178

On to step 3:
When dividing 213 by 178, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 35 after subtracting 178 from 213.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 178

Let's proceed to step 4:
When dividing 358 by 178, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 356 from 358 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 178

On to step 5:
When dividing 21 by 178, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 120.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 178

Advancing to step 6:
178 goes into 218 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1201.0
Subtracting 178 from 218 leaves us with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 178

Let's proceed to step 7:
178 goes into 401 2 times with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 12012.0
If we take 356 away from 401, we end up with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 178

Going ahead to step 8:
The number 178 fits into 459 2 times, leaving a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 120122.0
Subtracting 356 from 459 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 9:
1030 divided by 178 is 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 120122.5
If we subtract 890 from 1030, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
If we divide 1400 by 178, we get 7 and a remainder of 154.
The next digit of our result is 7. 
Result so far: 120122.57
Subtract 1246 from 1400 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 11:
1540 divided by 178 is 8 with a remainder of 116.
The next digit of our result is 8. 
Result so far: 120122.578
Subtract 1424 from 1540 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
178 can be fit into 1160 6 times, resulting in a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 120122.5786
The remainder is 92 after subtracting 1068 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
When dividing 920 by 178, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 120122.57865
If we subtract 890 from 920, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
178 goes into 300 1 times with a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 120122.578651
Deduct 178 from 300 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 15:
178 goes into 1220 6 times with a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 120122.5786516
The remainder is 152 after subtracting 1068 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 16:
1520 divided by 178 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 120122.57865168
If we subtract 1424 from 1520, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 120122.57865168 and a remainder of 9.6e-08.
