89953415 divided by 422 
We want to figure out the number of times 89953415 can be divided by 422.

Going ahead to step 1:
8 divided by 422 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 422

Step 2:
89 divided by 422 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 422

Let's proceed to step 3:
When dividing 899 by 422, we get 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 844 from 899, we get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 422

On to step 4:
422 can be fit into 555 1 times, resulting in a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 422 from 555 and we're left with 133.
Bring next digit (3) of the dividend behind the 133 and repeat the process: 1333 / 422

On to step 5:
When dividing 1333 by 422, we get 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Deduct 1266 from 1333 and we're left with 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 422

On to step 6:
674 divided by 422 is 1 with a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 2131.0
Subtracting 422 from 674 leaves us with 252.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 422

Moving on to step 7:
422 goes into 2521 5 times with a remainder of 411.
The number 5 becomes the next digit in our result. 
Result so far: 21315.0
Subtract 2110 from 2521 to get 411.
Take the next digit (5) from the dividend and append it to 411, then repeat: 4115 / 422

Let's proceed to step 8:
When dividing 4115 by 422, we get 9 with a remainder of 317.
The next digit of our result is 9. 
Result so far: 213159.0
Deduct 3798 from 4115 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 9:
The number 422 fits into 3170 7 times, leaving a remainder of 216.
Write down 7 as next digit of the result. 
Result so far: 213159.7
Subtract 2954 from 3170 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
The number 422 fits into 2160 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 213159.75
The remainder is 50 after subtracting 2110 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
The number 422 fits into 500 1 times, leaving a remainder of 78.
The next digit of our result is 1. 
Result so far: 213159.751
Subtract 422 from 500 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
If we divide 780 by 422, we get 1 and a remainder of 358.
Record the quotient 1 as the next digit in the result. 
Result so far: 213159.7511
If we subtract 422 from 780, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

The final result is 213159.7511 with a remainder of 0.00358.
