90022094 ÷ 621 
Our goal is to divide 90022094 by 621.

Let's proceed to step 1:
If we divide 9 by 621, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 621

Moving on to step 2:
If we divide 90 by 621, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 621

Step 3:
900 divided by 621 is 1 with a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 621 from 900 leaves us with 279.
Bring next digit (2) of the dividend behind the 279 and repeat the process: 2792 / 621

Let's proceed to step 4:
If we divide 2792 by 621, we get 4 and a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2484 from 2792 leaves us with 308.
Append the next digit (2) from the dividend to 308 and continue with: 3082 / 621

Moving on to step 5:
When dividing 3082 by 621, we get 4 with a remainder of 598.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Subtracting 2484 from 3082 leaves us with 598.
Fetch the next digit (0) from the dividend, attach it to 598 and continue: 5980 / 621

On to step 6:
621 can be fit into 5980 9 times, resulting in a remainder of 391.
Put 9 as the next digit of the answer. 
Result so far: 1449.0
Subtracting 5589 from 5980 leaves us with 391.
Bring next digit (9) of the dividend behind the 391 and repeat the process: 3919 / 621

On to step 7:
If we divide 3919 by 621, we get 6 and a remainder of 193.
The next digit of our result is 6. 
Result so far: 14496.0
The remainder is 193 after subtracting 3726 from 3919.
Take the next digit (4) from the dividend and append it to 193, then repeat: 1934 / 621

Step 8:
The number 621 fits into 1934 3 times, leaving a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 144963.0
If we subtract 1863 from 1934, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
710 divided by 621 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 144963.1
Subtract 621 from 710 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 10:
621 goes into 890 1 times with a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 144963.11
If we take 621 away from 890, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 144963.11, with a leftover of 0.269.
