Our goal is to divide 42025072 by 198.

On to step 1:
4 divided by 198 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 198

On to step 2:
If we divide 42 by 198, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 198

Advancing to step 3:
420 divided by 198 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 396 away from 420, we end up with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 198

Going ahead to step 4:
If we divide 242 by 198, we get 1 and a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 44 after subtracting 198 from 242.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 198

On to step 5:
198 goes into 445 2 times with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Deduct 396 from 445 and we're left with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 198

Step 6:
198 can be fit into 490 2 times, resulting in a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 2122.0
Deduct 396 from 490 and we're left with 94.
Fetch the next digit (7) from the dividend, attach it to 94 and continue: 947 / 198

Going ahead to step 7:
If we divide 947 by 198, we get 4 and a remainder of 155.
Write down 4 as next digit of the result. 
Result so far: 21224.0
Deduct 792 from 947 and we're left with 155.
Append the next digit (2) from the dividend to 155 and continue with: 1552 / 198

Advancing to step 8:
The number 198 fits into 1552 7 times, leaving a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 212247.0
Subtract 1386 from 1552 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 9:
The number 198 fits into 1660 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 212247.8
If we take 1584 away from 1660, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
760 divided by 198 is 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 212247.83
If we take 594 away from 760, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 11:
1660 divided by 198 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 212247.838
Subtract 1584 from 1660 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
When dividing 760 by 198, we get 3 with a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 212247.8383
Deduct 594 from 760 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 13:
198 can be fit into 1660 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 212247.83838
The remainder is 76 after subtracting 1584 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
When dividing 760 by 198, we get 3 with a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 212247.838383
If we take 594 away from 760, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 15:
198 can be fit into 1660 8 times, resulting in a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 212247.8383838
Subtract 1584 from 1660 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 16:
If we divide 760 by 198, we get 3 and a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 212247.83838383
The remainder is 166 after subtracting 594 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 212247.83838383 with a remainder of 1.66e-07.
