193975 divided by 90 
Our goal is to divide 193975 by 90.

Moving on to step 1:
90 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 90

Going ahead to step 2:
When dividing 19 by 90, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 90

Advancing to step 3:
If we divide 193 by 90, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 180 from 193, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 90

Let's proceed to step 4:
The number 90 fits into 139 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 21.0
If we take 90 away from 139, we end up with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 90

Advancing to step 5:
The number 90 fits into 497 5 times, leaving a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 215.0
The remainder is 47 after subtracting 450 from 497.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 90

Advancing to step 6:
475 divided by 90 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2155.0
If we take 450 away from 475, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
90 can be fit into 250 2 times, resulting in a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 2155.2
If we take 180 away from 250, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 2155.27
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
700 divided by 90 is 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 2155.277
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 2155.277, with a leftover of 0.007.
