We're dividing 903658 by 73 
We want to divide 903658 by 73.

Step 1:
73 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 73

On to step 2:
The number 73 fits into 90 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 73 from 90 and we're left with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 73

Going ahead to step 3:
When dividing 173 by 73, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 146 from 173 to get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 73

Moving on to step 4:
The number 73 fits into 276 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we take 219 away from 276, we end up with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 73

Step 5:
The number 73 fits into 575 7 times, leaving a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 1237.0
Subtracting 511 from 575 leaves us with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 73

On to step 6:
73 goes into 648 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 12378.0
Subtracting 584 from 648 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
When dividing 640 by 73, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 12378.8
If we take 584 away from 640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
73 goes into 560 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 12378.87
Subtract 511 from 560 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
If we divide 490 by 73, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 12378.876
Subtracting 438 from 490 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
When dividing 520 by 73, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 12378.8767
Subtracting 511 from 520 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
73 can be fit into 90 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 12378.87671
The remainder is 17 after subtracting 73 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
73 can be fit into 170 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12378.876712
Subtracting 146 from 170 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
When dividing 240 by 73, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 12378.8767123
Subtract 219 from 240 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
210 divided by 73 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 12378.87671232
Subtracting 146 from 210 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 12378.87671232 and a remainder of 6.4e-08.
