We divide 948403 by 90
We want to figure out the number of times 948403 can be divided by 90.

Going ahead to step 1:
90 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 90

Advancing to step 2:
If we divide 94 by 90, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 4 after subtracting 90 from 94.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 90

Step 3:
90 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 48, we get 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 90

Going ahead to step 4:
90 goes into 484 5 times with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 105.0
Deduct 450 from 484 and we're left with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 90

Step 5:
340 divided by 90 is 3 with a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 1053.0
Subtracting 270 from 340 leaves us with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 90

Advancing to step 6:
90 goes into 703 7 times with a remainder of 73.
The next digit of our result is 7. 
Result so far: 10537.0
Deduct 630 from 703 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
90 can be fit into 730 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 10537.8
If we take 720 away from 730, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 10537.81
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 90 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 10537.811
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 10537.811 and a remainder of 0.001.
