We divide 72873547 by 170
We want to divide 72873547 by 170.

Let's proceed to step 1:
When dividing 7 by 170, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 170

Moving on to step 2:
The number 170 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 170

Moving on to step 3:
When dividing 728 by 170, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 680 from 728 and we're left with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 170

Going ahead to step 4:
If we divide 487 by 170, we get 2 and a remainder of 147.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 340 from 487 and we're left with 147.
Include the next digit (3) from the dividend after 147, then repeat: 1473 / 170

Advancing to step 5:
The number 170 fits into 1473 8 times, leaving a remainder of 113.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
The remainder is 113 after subtracting 1360 from 1473.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 170

Advancing to step 6:
1135 divided by 170 is 6 with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 4286.0
If we take 1020 away from 1135, we end up with 115.
Include the next digit (4) from the dividend after 115, then repeat: 1154 / 170

Advancing to step 7:
170 can be fit into 1154 6 times, resulting in a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 42866.0
Subtracting 1020 from 1154 leaves us with 134.
Include the next digit (7) from the dividend after 134, then repeat: 1347 / 170

Step 8:
170 goes into 1347 7 times with a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 428667.0
If we subtract 1190 from 1347, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
If we divide 1570 by 170, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 428667.9
Subtract 1530 from 1570 to get 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 10:
170 goes into 400 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 428667.92
If we take 340 away from 400, we end up 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.

Step 11:
The number 170 fits into 600 3 times, leaving a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 428667.923
If we take 510 away from 600, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
The number 170 fits into 900 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 428667.9235
Subtract 850 from 900 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
170 can be fit into 500 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 428667.92352
Subtract 340 from 500 to 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 14:
1600 divided by 170 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 428667.923529
Subtract 1530 from 1600 to 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 15:
If we divide 700 by 170, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 428667.9235294
If we take 680 away from 700, we end up 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.

Going ahead to step 16:
200 divided by 170 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 428667.92352941
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 428667.92352941 and a remainder of 3e-08.
