20103017 divided by 953 
We want to figure out the number of times 20103017 can be divided by 953.

Step 1:
953 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 953

Step 2:
The number 953 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 953

On to step 3:
201 divided by 953 is 0 with a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Append the next digit (0) from the dividend to 201 and continue with: 2010 / 953

On to step 4:
If we divide 2010 by 953, we get 2 and a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1906 from 2010 and we're left with 104.
Bring next digit (3) of the dividend behind the 104 and repeat the process: 1043 / 953

On to step 5:
The number 953 fits into 1043 1 times, leaving a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 953 away from 1043, we end up with 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 953

Advancing to step 6:
The number 953 fits into 900 0 times, leaving a remainder of 900.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we subtract 0 from 900, we get 900.
Grab the next digit (1) from the dividend, add it to 900, then carry on: 9001 / 953

On to step 7:
The number 953 fits into 9001 9 times, leaving a remainder of 424.
Use 9 as the next digit of our solution. 
Result so far: 2109.0
Subtracting 8577 from 9001 leaves us with 424.
Bring next digit (7) of the dividend behind the 424 and repeat the process: 4247 / 953

On to step 8:
The number 953 fits into 4247 4 times, leaving a remainder of 435.
Write down 4 as next digit of the result. 
Result so far: 21094.0
Subtracting 3812 from 4247 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 9:
The number 953 fits into 4350 4 times, leaving a remainder of 538.
The next digit of our result is 4. 
Result so far: 21094.4
Deduct 3812 from 4350 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 10:
If we divide 5380 by 953, we get 5 and a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 21094.45
If we take 4765 away from 5380, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 11:
If we divide 6150 by 953, we get 6 and a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 21094.456
Deduct 5718 from 6150 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 12:
The number 953 fits into 4320 4 times, leaving a remainder of 508.
The next digit of our result is 4. 
Result so far: 21094.4564
Subtract 3812 from 4320 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 13:
If we divide 5080 by 953, we get 5 and a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 21094.45645
If we subtract 4765 from 5080, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 14:
3150 divided by 953 is 3 with a remainder of 291.
Use 3 as the next digit of our solution. 
Result so far: 21094.456453
The remainder is 291 after subtracting 2859 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 15:
If we divide 2910 by 953, we get 3 and a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 21094.4564533
If we take 2859 away from 2910, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 21094.4564533 with a remainder of 5.1e-07.
