We're dividing 15973488 by 170 
We want to divide 15973488 by 170.

On to step 1:
170 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 170

Step 2:
The number 170 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 170

Let's proceed to step 3:
If we divide 159 by 170, we get 0 and a remainder of 159.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Fetch the next digit (7) from the dividend, attach it to 159 and continue: 1597 / 170

On to step 4:
If we divide 1597 by 170, we get 9 and a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 1530 from 1597 leaves us with 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 170

Step 5:
When dividing 673 by 170, we get 3 with a remainder of 163.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 510 away from 673, we end up with 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 170

Advancing to step 6:
The number 170 fits into 1634 9 times, leaving a remainder of 104.
The next digit of our result is 9. 
Result so far: 939.0
If we take 1530 away from 1634, we end up with 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 170

On to step 7:
170 goes into 1048 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 9396.0
Subtracting 1020 from 1048 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 170

Advancing to step 8:
The number 170 fits into 288 1 times, leaving a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 93961.0
Subtracting 170 from 288 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 9:
170 can be fit into 1180 6 times, resulting in a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 93961.6
Subtracting 1020 from 1180 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
170 goes into 1600 9 times with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 93961.69
The remainder is 70 after subtracting 1530 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
If we divide 700 by 170, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 93961.694
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
170 can be fit into 200 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 93961.6941
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
170 goes into 300 1 times with a remainder of 130.
Record the quotient 1 as the next digit in the result. 
Result so far: 93961.69411
The remainder is 130 after subtracting 170 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 93961.69411, and the remainder is 0.00013.
