We look at the division of 197805 by 51 
We want to figure out the number of times 197805 can be divided by 51.

On to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 51

Advancing to step 2:
51 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 51

Let's proceed to step 3:
If we divide 197 by 51, we get 3 and a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 153 from 197, we get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 51

Going ahead to step 4:
448 divided by 51 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 408 from 448 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 51

Advancing to step 5:
51 can be fit into 400 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 387.0
If we subtract 357 from 400, we get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 51

Let's proceed to step 6:
435 divided by 51 is 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 3878.0
If we subtract 408 from 435, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3878.5
If we take 255 away from 270, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
150 divided by 51 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 3878.52
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
When dividing 480 by 51, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 3878.529
If we subtract 459 from 480, we 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.

Let's proceed to step 10:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 3878.5294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
When dividing 60 by 51, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 3878.52941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 3878.529411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 3878.529411 with a remainder of 3.9e-06.
