We're dividing 51586885 by 203 
Our goal is to divide 51586885 by 203.

On to step 1:
203 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 203

Going ahead to step 2:
The number 203 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 203

Going ahead to step 3:
515 divided by 203 is 2 with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 109 after subtracting 406 from 515.
Append the next digit (8) from the dividend to 109 and continue with: 1098 / 203

Let's proceed to step 4:
When dividing 1098 by 203, we get 5 with a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 83 after subtracting 1015 from 1098.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 203

Let's proceed to step 5:
203 can be fit into 836 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 812 from 836 to get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 203

Advancing to step 6:
When dividing 248 by 203, we get 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 2541.0
Subtracting 203 from 248 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 203

On to step 7:
458 divided by 203 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 25412.0
If we take 406 away from 458, we end up with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 203

On to step 8:
The number 203 fits into 525 2 times, leaving a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 254122.0
Deduct 406 from 525 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 9:
203 can be fit into 1190 5 times, resulting in a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 254122.5
If we take 1015 away from 1190, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 10:
203 goes into 1750 8 times with a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 254122.58
Subtracting 1624 from 1750 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 11:
203 goes into 1260 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 254122.586
Subtract 1218 from 1260 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 203, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 254122.5862
Deduct 406 from 420 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
The number 203 fits into 140 0 times, leaving a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 254122.5862
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 14:
When dividing 1400 by 203, we get 6 with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 254122.586206
Subtracting 1218 from 1400 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 15:
When dividing 1820 by 203, we get 8 with a remainder of 196.
The next digit of our result is 8. 
Result so far: 254122.5862068
Deduct 1624 from 1820 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 16:
203 can be fit into 1960 9 times, resulting in a remainder of 133.
Record the quotient 9 as the next digit in the result. 
Result so far: 254122.58620689
Deduct 1827 from 1960 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The final outcome is 254122.58620689, with a leftover of 1.33e-07.
