We're dividing 21572782 by 122 
We want to figure out the number of times 21572782 can be divided by 122.

Going ahead to step 1:
2 divided by 122 is 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 / 122

Let's proceed to step 2:
21 divided by 122 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 122

Step 3:
122 goes into 215 1 times with a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 122 from 215 and we're left with 93.
Fetch the next digit (7) from the dividend, attach it to 93 and continue: 937 / 122

Moving on to step 4:
122 goes into 937 7 times with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 854 from 937 and we're left with 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 122

Let's proceed to step 5:
If we divide 832 by 122, we get 6 and a remainder of 100.
The next digit of our result is 6. 
Result so far: 176.0
Subtract 732 from 832 to get 100.
Fetch the next digit (7) from the dividend, attach it to 100 and continue: 1007 / 122

Going ahead to step 6:
1007 divided by 122 is 8 with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 1768.0
The remainder is 31 after subtracting 976 from 1007.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 122

Advancing to step 7:
The number 122 fits into 318 2 times, leaving a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 17682.0
Subtract 244 from 318 to get 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 122

Step 8:
When dividing 742 by 122, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 176826.0
The remainder is 10 after subtracting 732 from 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 122 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 176826.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
1000 divided by 122 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 176826.08
Deduct 976 from 1000 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
240 divided by 122 is 1 with a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 176826.081
Subtract 122 from 240 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 12:
122 can be fit into 1180 9 times, resulting in a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 176826.0819
Deduct 1098 from 1180 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 13:
122 goes into 820 6 times with a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 176826.08196
Subtract 732 from 820 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
The number 122 fits into 880 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 176826.081967
If we take 854 away from 880, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 15:
When dividing 260 by 122, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 176826.0819672
If we take 244 away from 260, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
122 can be fit into 160 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 176826.08196721
If we take 122 away from 160, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 176826.08196721 with a remaining 3.8e-08.
