We're dividing 73961545 by 170 
Let's see how many times 170 fits into 73961545.

On to step 1:
170 goes into 7 0 times with 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.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 170

Let's proceed to step 2:
73 divided by 170 is 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 170

Let's proceed to step 3:
739 divided by 170 is 4 with a remainder of 59.
The next digit of our result is 4. 
Result so far: 4.0
If we take 680 away from 739, we end up with 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 170

Moving on to step 4:
If we divide 596 by 170, we get 3 and a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 510 from 596 to get 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 170

Going ahead to step 5:
861 divided by 170 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we subtract 850 from 861, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 170

Going ahead to step 6:
170 goes into 115 0 times with a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 4350.0
Subtract 0 from 115 to get 115.
Grab the next digit (4) from the dividend, add it to 115, then carry on: 1154 / 170

Moving on to step 7:
If we divide 1154 by 170, we get 6 and a remainder of 134.
The next digit of our result is 6. 
Result so far: 43506.0
If we take 1020 away from 1154, we end up with 134.
Bring next digit (5) of the dividend behind the 134 and repeat the process: 1345 / 170

Going ahead to step 8:
170 can be fit into 1345 7 times, resulting in a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 435067.0
If we take 1190 away from 1345, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 9:
170 can be fit into 1550 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 435067.9
If we subtract 1530 from 1550, 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.

On to step 10:
170 can be fit into 200 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 435067.91
Subtract 170 from 200 to get 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 11:
The number 170 fits into 300 1 times, leaving a remainder of 130.
Record the quotient 1 as the next digit in the result. 
Result so far: 435067.911
Subtracting 170 from 300 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 435067.911 with a remaining 0.013.
