We look at the division of 21529035 by 170 
We're looking to find how many times 170 goes into 21529035.

Going ahead to step 1:
When dividing 2 by 170, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 170

Let's proceed to step 2:
When dividing 21 by 170, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 170

Step 3:
170 can be fit into 215 1 times, resulting in a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 170 from 215, we get 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 170

Let's proceed to step 4:
452 divided by 170 is 2 with a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 340 from 452 and we're left with 112.
Take the next digit (9) from the dividend and append it to 112, then repeat: 1129 / 170

Going ahead to step 5:
170 can be fit into 1129 6 times, resulting in a remainder of 109.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 1020 away from 1129, we end up with 109.
Take the next digit (0) from the dividend and append it to 109, then repeat: 1090 / 170

Going ahead to step 6:
If we divide 1090 by 170, we get 6 and a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 1266.0
Subtracting 1020 from 1090 leaves us with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 170

Step 7:
If we divide 703 by 170, we get 4 and a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 12664.0
Subtracting 680 from 703 leaves us with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 170

Moving on to step 8:
The number 170 fits into 235 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 126641.0
Subtracting 170 from 235 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
The number 170 fits into 650 3 times, leaving a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 126641.3
Deduct 510 from 650 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
170 can be fit into 1400 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 126641.38
If we take 1360 away from 1400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 170 fits into 400 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 126641.382
Subtracting 340 from 400 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.

Going ahead to step 12:
170 can be fit into 600 3 times, resulting in a remainder of 90.
The next digit of our result is 3. 
Result so far: 126641.3823
Subtract 510 from 600 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
When dividing 900 by 170, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 126641.38235
If we take 850 away from 900, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 170 fits into 500 2 times, leaving a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 126641.382352
If we subtract 340 from 500, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
The number 170 fits into 1600 9 times, leaving a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 126641.3823529
If we subtract 1530 from 1600, 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.

Moving on to step 16:
170 goes into 700 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 126641.38235294
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 126641.38235294, and the remainder is 2e-08.
