19752215 ÷ 170 
Our goal is to divide 19752215 by 170.

Step 1:
170 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 170

On to step 2:
170 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 170

Moving on to step 3:
197 divided by 170 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 170 away from 197, we end up with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 170

Moving on to step 4:
The number 170 fits into 275 1 times, leaving a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 170 from 275 and we're left with 105.
Grab the next digit (2) from the dividend, add it to 105, then carry on: 1052 / 170

Let's proceed to step 5:
When dividing 1052 by 170, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 1020 from 1052, we get 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 170

Step 6:
322 divided by 170 is 1 with a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 1161.0
If we take 170 away from 322, we end up with 152.
Include the next digit (1) from the dividend after 152, then repeat: 1521 / 170

Let's proceed to step 7:
If we divide 1521 by 170, we get 8 and a remainder of 161.
Put 8 as the next digit of the answer. 
Result so far: 11618.0
Deduct 1360 from 1521 and we're left with 161.
Fetch the next digit (5) from the dividend, attach it to 161 and continue: 1615 / 170

Let's proceed to step 8:
170 can be fit into 1615 9 times, resulting in a remainder of 85.
The next digit of our result is 9. 
Result so far: 116189.0
Subtract 1530 from 1615 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
The number 170 fits into 850 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 116189.5
If we subtract 850 from 850, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 170, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 116189.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 170 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 116189.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 116189.5 with a remaining 0.0.
