We look at the division of 45186303 by 170 
We're looking to find how many times 170 goes into 45186303.

Going ahead to step 1:
4 divided by 170 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 170

Moving on to step 2:
170 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 170

On to step 3:
170 goes into 451 2 times with a remainder of 111.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 111 after subtracting 340 from 451.
Grab the next digit (8) from the dividend, add it to 111, then carry on: 1118 / 170

Moving on to step 4:
If we divide 1118 by 170, we get 6 and a remainder of 98.
The next digit of our result is 6. 
Result so far: 26.0
If we take 1020 away from 1118, we end up with 98.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 170

Going ahead to step 5:
170 goes into 986 5 times with a remainder of 136.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
The remainder is 136 after subtracting 850 from 986.
Append the next digit (3) from the dividend to 136 and continue with: 1363 / 170

Going ahead to step 6:
The number 170 fits into 1363 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 2658.0
Subtract 1360 from 1363 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 170

On to step 7:
170 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 26580.0
If we take 0 away from 30, we end up with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 170

Moving on to step 8:
When dividing 303 by 170, we get 1 with a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 265801.0
Subtract 170 from 303 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
170 can be fit into 1330 7 times, resulting in a remainder of 140.
Record the quotient 7 as the next digit in the result. 
Result so far: 265801.7
If we subtract 1190 from 1330, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
170 goes into 1400 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 265801.78
The remainder is 40 after subtracting 1360 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
170 can be fit into 400 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 265801.782
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
600 divided by 170 is 3 with a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 265801.7823
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.

Going ahead to step 13:
170 goes into 900 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 265801.78235
If we take 850 away from 900, we end up 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.

Advancing to step 14:
500 divided by 170 is 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 265801.782352
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.

Moving on to step 15:
The number 170 fits into 1600 9 times, leaving a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 265801.7823529
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.

Going ahead to step 16:
700 divided by 170 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 265801.78235294
Subtract 680 from 700 to 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.

The quotient of the division is 265801.78235294, and the remainder is 2e-08.
