Let's divide 90421303 by 569
We want to figure out the number of times 90421303 can be divided by 569.

Advancing to step 1:
When dividing 9 by 569, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 569

Step 2:
The number 569 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 569

On to step 3:
904 divided by 569 is 1 with a remainder of 335.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 569 from 904 and we're left with 335.
Grab the next digit (2) from the dividend, add it to 335, then carry on: 3352 / 569

Going ahead to step 4:
When dividing 3352 by 569, we get 5 with a remainder of 507.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 507 after subtracting 2845 from 3352.
Bring next digit (1) of the dividend behind the 507 and repeat the process: 5071 / 569

Moving on to step 5:
The number 569 fits into 5071 8 times, leaving a remainder of 519.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
The remainder is 519 after subtracting 4552 from 5071.
Grab the next digit (3) from the dividend, add it to 519, then carry on: 5193 / 569

Going ahead to step 6:
569 can be fit into 5193 9 times, resulting in a remainder of 72.
The next digit of our result is 9. 
Result so far: 1589.0
Subtract 5121 from 5193 to get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 569

Let's proceed to step 7:
When dividing 720 by 569, we get 1 with a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 15891.0
If we subtract 569 from 720, we get 151.
Append the next digit (3) from the dividend to 151 and continue with: 1513 / 569

On to step 8:
569 can be fit into 1513 2 times, resulting in a remainder of 375.
The number 2 becomes the next digit in our result. 
Result so far: 158912.0
Subtracting 1138 from 1513 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 9:
3750 divided by 569 is 6 with a remainder of 336.
The number 6 becomes the next digit in our result. 
Result so far: 158912.6
Subtract 3414 from 3750 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 10:
If we divide 3360 by 569, we get 5 and a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 158912.65
If we subtract 2845 from 3360, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 11:
5150 divided by 569 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 158912.659
Subtracting 5121 from 5150 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
The number 569 fits into 290 0 times, leaving a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 158912.659
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 13:
If we divide 2900 by 569, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 158912.65905
Subtract 2845 from 2900 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
550 divided by 569 is 0 with a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 158912.65905
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 15:
The number 569 fits into 5500 9 times, leaving a remainder of 379.
Put 9 as the next digit of the answer. 
Result so far: 158912.6590509
Subtracting 5121 from 5500 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 16:
The number 569 fits into 3790 6 times, leaving a remainder of 376.
The next digit of our result is 6. 
Result so far: 158912.65905096
Subtract 3414 from 3790 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 158912.65905096, with a leftover of 3.76e-07.
