We're dividing 60139649 by 903 
Let's see how many times 903 fits into 60139649.

Advancing to step 1:
The number 903 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 903

On to step 2:
When dividing 60 by 903, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 903

On to step 3:
If we divide 601 by 903, we get 0 and a remainder of 601.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 601, we get 601.
Bring next digit (3) of the dividend behind the 601 and repeat the process: 6013 / 903

Let's proceed to step 4:
When dividing 6013 by 903, we get 6 with a remainder of 595.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 5418 from 6013, we get 595.
Grab the next digit (9) from the dividend, add it to 595, then carry on: 5959 / 903

Advancing to step 5:
The number 903 fits into 5959 6 times, leaving a remainder of 541.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 541 after subtracting 5418 from 5959.
Take the next digit (6) from the dividend and append it to 541, then repeat: 5416 / 903

Step 6:
903 can be fit into 5416 5 times, resulting in a remainder of 901.
Put 5 as the next digit of the answer. 
Result so far: 665.0
If we subtract 4515 from 5416, we get 901.
Grab the next digit (4) from the dividend, add it to 901, then carry on: 9014 / 903

Let's proceed to step 7:
When dividing 9014 by 903, we get 9 with a remainder of 887.
Put 9 as the next digit of the answer. 
Result so far: 6659.0
Subtract 8127 from 9014 to get 887.
Grab the next digit (9) from the dividend, add it to 887, then carry on: 8879 / 903

Let's proceed to step 8:
8879 divided by 903 is 9 with a remainder of 752.
Record the quotient 9 as the next digit in the result. 
Result so far: 66599.0
The remainder is 752 after subtracting 8127 from 8879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 9:
7520 divided by 903 is 8 with a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 66599.8
If we subtract 7224 from 7520, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
2960 divided by 903 is 3 with a remainder of 251.
Write down 3 as next digit of the result. 
Result so far: 66599.83
Deduct 2709 from 2960 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 11:
When dividing 2510 by 903, we get 2 with a remainder of 704.
Use 2 as the next digit of our solution. 
Result so far: 66599.832
If we take 1806 away from 2510, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 12:
If we divide 7040 by 903, we get 7 and a remainder of 719.
Use 7 as the next digit of our solution. 
Result so far: 66599.8327
Subtracting 6321 from 7040 leaves us with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Moving on to step 13:
When dividing 7190 by 903, we get 7 with a remainder of 869.
Use 7 as the next digit of our solution. 
Result so far: 66599.83277
The remainder is 869 after subtracting 6321 from 7190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

The final result is 66599.83277 with a remainder of 0.000869.
