We're dividing 42393026 by 197 
We want to figure out the number of times 42393026 can be divided by 197.

On to step 1:
If we divide 4 by 197, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 197

On to step 2:
197 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 197

Step 3:
197 goes into 423 2 times with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 394 from 423 to get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 197

Step 4:
When dividing 299 by 197, we get 1 with a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 197 away from 299, we end up with 102.
Take the next digit (3) from the dividend and append it to 102, then repeat: 1023 / 197

Let's proceed to step 5:
When dividing 1023 by 197, we get 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Deduct 985 from 1023 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 197

Moving on to step 6:
197 can be fit into 380 1 times, resulting in a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 2151.0
If we take 197 away from 380, we end up with 183.
Bring next digit (2) of the dividend behind the 183 and repeat the process: 1832 / 197

Going ahead to step 7:
When dividing 1832 by 197, we get 9 with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 21519.0
Subtracting 1773 from 1832 leaves us with 59.
Grab the next digit (6) from the dividend, add it to 59, then carry on: 596 / 197

Moving on to step 8:
197 can be fit into 596 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 215193.0
Subtracting 591 from 596 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 197, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 215193.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 197, we get 2 and a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 215193.02
Deduct 394 from 500 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
The number 197 fits into 1060 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 215193.025
If we take 985 away from 1060, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
If we divide 750 by 197, we get 3 and a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 215193.0253
If we take 591 away from 750, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 13:
197 can be fit into 1590 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 215193.02538
The remainder is 14 after subtracting 1576 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
140 divided by 197 is 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 215193.02538
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
When dividing 1400 by 197, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 215193.0253807
Subtract 1379 from 1400 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
197 can be fit into 210 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 215193.02538071
Subtracting 197 from 210 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 215193.02538071 and a remainder of 1.3e-08.
