We look at the division of 58645966 by 903 
We want to divide 58645966 by 903.

Going ahead to step 1:
If we divide 5 by 903, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 903

Going ahead to step 2:
58 divided by 903 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 903

Going ahead to step 3:
If we divide 586 by 903, we get 0 and a remainder of 586.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 586, we get 586.
Append the next digit (4) from the dividend to 586 and continue with: 5864 / 903

Let's proceed to step 4:
If we divide 5864 by 903, we get 6 and a remainder of 446.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 446 after subtracting 5418 from 5864.
Take the next digit (5) from the dividend and append it to 446, then repeat: 4465 / 903

Advancing to step 5:
4465 divided by 903 is 4 with a remainder of 853.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 3612 from 4465 and we're left with 853.
Take the next digit (9) from the dividend and append it to 853, then repeat: 8539 / 903

Let's proceed to step 6:
When dividing 8539 by 903, we get 9 with a remainder of 412.
The number 9 becomes the next digit in our result. 
Result so far: 649.0
The remainder is 412 after subtracting 8127 from 8539.
Grab the next digit (6) from the dividend, add it to 412, then carry on: 4126 / 903

Step 7:
903 can be fit into 4126 4 times, resulting in a remainder of 514.
Use 4 as the next digit of our solution. 
Result so far: 6494.0
If we take 3612 away from 4126, we end up with 514.
Take the next digit (6) from the dividend and append it to 514, then repeat: 5146 / 903

Going ahead to step 8:
5146 divided by 903 is 5 with a remainder of 631.
The number 5 becomes the next digit in our result. 
Result so far: 64945.0
The remainder is 631 after subtracting 4515 from 5146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Let's proceed to step 9:
If we divide 6310 by 903, we get 6 and a remainder of 892.
Use 6 as the next digit of our solution. 
Result so far: 64945.6
The remainder is 892 after subtracting 5418 from 6310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

On to step 10:
If we divide 8920 by 903, we get 9 and a remainder of 793.
The next digit of our result is 9. 
Result so far: 64945.69
Subtract 8127 from 8920 to get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Step 11:
7930 divided by 903 is 8 with a remainder of 706.
Put 8 as the next digit of the answer. 
Result so far: 64945.698
Subtracting 7224 from 7930 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 12:
903 goes into 7060 7 times with a remainder of 739.
The number 7 becomes the next digit in our result. 
Result so far: 64945.6987
If we take 6321 away from 7060, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Moving on to step 13:
The number 903 fits into 7390 8 times, leaving a remainder of 166.
Record the quotient 8 as the next digit in the result. 
Result so far: 64945.69878
The remainder is 166 after subtracting 7224 from 7390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 14:
If we divide 1660 by 903, we get 1 and a remainder of 757.
The next digit of our result is 1. 
Result so far: 64945.698781
The remainder is 757 after subtracting 903 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Going ahead to step 15:
7570 divided by 903 is 8 with a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 64945.6987818
If we subtract 7224 from 7570, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 16:
The number 903 fits into 3460 3 times, leaving a remainder of 751.
Write down 3 as next digit of the result. 
Result so far: 64945.69878183
If we subtract 2709 from 3460, we get 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

The final result is 64945.69878183 with a remainder of 7.51e-07.
