We're dividing 198629 by 51 
We want to figure out the number of times 198629 can be divided by 51.

Going ahead to step 1:
51 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 51

Advancing to step 2:
51 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 51

Moving on to step 3:
51 can be fit into 198 3 times, resulting in a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 153 from 198 and we're left with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 51

Moving on to step 4:
51 goes into 456 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 408 from 456 leaves us with 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 51

Let's proceed to step 5:
51 goes into 482 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 389.0
The remainder is 23 after subtracting 459 from 482.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 51

Step 6:
239 divided by 51 is 4 with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 3894.0
Subtracting 204 from 239 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
If we divide 350 by 51, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 3894.6
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
If we divide 440 by 51, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3894.68
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
When dividing 320 by 51, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 3894.686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 3894.6862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
If we divide 380 by 51, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 3894.68627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 3894.686274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
If we divide 260 by 51, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3894.6862745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
If we divide 50 by 51, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 3894.6862745
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.

Our division results in 3894.6862745 with a remaining 5e-08.
