We're dividing 21705397 by 142 
Let's see how many times 142 fits into 21705397.

Let's proceed to step 1:
If we divide 2 by 142, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 142

Let's proceed to step 2:
When dividing 21 by 142, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 142

Moving on to step 3:
When dividing 217 by 142, we get 1 with a remainder of 75.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 142 from 217 leaves us with 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 142

Let's proceed to step 4:
If we divide 750 by 142, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 710 away from 750, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 142

Advancing to step 5:
When dividing 405 by 142, we get 2 with a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 284 from 405, we get 121.
Fetch the next digit (3) from the dividend, attach it to 121 and continue: 1213 / 142

Advancing to step 6:
142 can be fit into 1213 8 times, resulting in a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 1528.0
Subtract 1136 from 1213 to get 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 142

Moving on to step 7:
If we divide 779 by 142, we get 5 and a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 15285.0
Subtract 710 from 779 to get 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 142

Let's proceed to step 8:
697 divided by 142 is 4 with a remainder of 129.
Write down 4 as next digit of the result. 
Result so far: 152854.0
Subtract 568 from 697 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 9:
142 can be fit into 1290 9 times, resulting in a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 152854.9
The remainder is 12 after subtracting 1278 from 1290.
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:
If we divide 120 by 142, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 152854.9
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
142 can be fit into 1200 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 152854.908
The remainder is 64 after subtracting 1136 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
When dividing 640 by 142, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 152854.9084
Deduct 568 from 640 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
720 divided by 142 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 152854.90845
Deduct 710 from 720 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 142, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 152854.90845
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
If we divide 1000 by 142, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 152854.9084507
Deduct 994 from 1000 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
When dividing 60 by 142, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 152854.9084507
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 152854.9084507, and the remainder is 6e-08.
