Advancing to step 1:
197 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 197

Going ahead to step 2:
197 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 197

Moving on to step 3:
197 can be fit into 815 4 times, resulting in a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 788 from 815 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 197

On to step 4:
The number 197 fits into 273 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 41.0
If we take 197 away from 273, we end up with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 197

On to step 5:
If we divide 768 by 197, we get 3 and a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 413.0
Subtracting 591 from 768 leaves us with 177.
Grab the next digit (1) from the dividend, add it to 177, then carry on: 1771 / 197

Let's proceed to step 6:
1771 divided by 197 is 8 with a remainder of 195.
Put 8 as the next digit of the answer. 
Result so far: 4138.0
Subtract 1576 from 1771 to get 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 197

Let's proceed to step 7:
If we divide 1956 by 197, we get 9 and a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 41389.0
Subtracting 1773 from 1956 leaves us with 183.
Take the next digit (5) from the dividend and append it to 183, then repeat: 1835 / 197

Step 8:
The number 197 fits into 1835 9 times, leaving a remainder of 62.
The next digit of our result is 9. 
Result so far: 413899.0
Subtracting 1773 from 1835 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
The number 197 fits into 620 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 413899.3
Deduct 591 from 620 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
The number 197 fits into 290 1 times, leaving a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 413899.31
Subtracting 197 from 290 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 11:
930 divided by 197 is 4 with a remainder of 142.
The number 4 becomes the next digit in our result. 
Result so far: 413899.314
If we take 788 away from 930, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 12:
1420 divided by 197 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 413899.3147
If we subtract 1379 from 1420, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
410 divided by 197 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 413899.31472
The remainder is 16 after subtracting 394 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
197 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 413899.31472
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
If we divide 1600 by 197, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 413899.3147208
Deduct 1576 from 1600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
197 can be fit into 240 1 times, resulting in a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 413899.31472081
If we take 197 away from 240, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 413899.31472081 with a balance of 4.3e-08.
