73580920 ÷ 170 
Our goal is to divide 73580920 by 170.

Step 1:
If we divide 7 by 170, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 170

Advancing to step 2:
When dividing 73 by 170, we get 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 170

Going ahead to step 3:
735 divided by 170 is 4 with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 680 away from 735, we end up with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 170

Moving on to step 4:
558 divided by 170 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 510 from 558 to get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 170

On to step 5:
If we divide 480 by 170, we get 2 and a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 432.0
If we take 340 away from 480, we end up with 140.
Fetch the next digit (9) from the dividend, attach it to 140 and continue: 1409 / 170

Step 6:
170 goes into 1409 8 times with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 4328.0
The remainder is 49 after subtracting 1360 from 1409.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 170

On to step 7:
492 divided by 170 is 2 with a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 43282.0
The remainder is 152 after subtracting 340 from 492.
Bring next digit (0) of the dividend behind the 152 and repeat the process: 1520 / 170

Moving on to step 8:
170 can be fit into 1520 8 times, resulting in a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 432828.0
Subtract 1360 from 1520 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.

On to step 9:
The number 170 fits into 1600 9 times, leaving a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 432828.9
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.

Going ahead to step 10:
When dividing 700 by 170, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 432828.94
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.

Advancing to step 11:
If we divide 200 by 170, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 432828.941
Subtracting 170 from 200 leaves us 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 12:
When dividing 300 by 170, we get 1 with a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 432828.9411
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 final outcome is 432828.9411, with a leftover of 0.0013.
