We look at the division of 45211250 by 170 
We want to figure out the number of times 45211250 can be divided by 170.

On to step 1:
170 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 170

Moving on to step 2:
If we divide 45 by 170, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 170

Moving on to step 3:
170 goes into 452 2 times with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 340 from 452, we get 112.
Include the next digit (1) from the dividend after 112, then repeat: 1121 / 170

Let's proceed to step 4:
When dividing 1121 by 170, we get 6 with a remainder of 101.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 1020 away from 1121, we end up with 101.
Take the next digit (1) from the dividend and append it to 101, then repeat: 1011 / 170

Advancing to step 5:
170 can be fit into 1011 5 times, resulting in a remainder of 161.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
The remainder is 161 after subtracting 850 from 1011.
Grab the next digit (2) from the dividend, add it to 161, then carry on: 1612 / 170

On to step 6:
When dividing 1612 by 170, we get 9 with a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 2659.0
If we take 1530 away from 1612, we end up with 82.
Fetch the next digit (5) from the dividend, attach it to 82 and continue: 825 / 170

Let's proceed to step 7:
When dividing 825 by 170, we get 4 with a remainder of 145.
Put 4 as the next digit of the answer. 
Result so far: 26594.0
Deduct 680 from 825 and we're left with 145.
Fetch the next digit (0) from the dividend, attach it to 145 and continue: 1450 / 170

Advancing to step 8:
When dividing 1450 by 170, we get 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 265948.0
If we subtract 1360 from 1450, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 9:
If we divide 900 by 170, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 265948.5
Deduct 850 from 900 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
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: 265948.52
If we take 340 away from 500, we end up 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.

Step 11:
1600 divided by 170 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 265948.529
Subtracting 1530 from 1600 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
700 divided by 170 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 265948.5294
Deduct 680 from 700 and we're left 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.

Moving on to step 13:
When dividing 200 by 170, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 265948.52941
If we subtract 170 from 200, we 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 14:
170 goes into 300 1 times with a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 265948.529411
Deduct 170 from 300 and we're left 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.

The final result is 265948.529411 with a remainder of 1.3e-05.
