On to step 4:
39 can be fit into 161 4 times, resulting in a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 204.0
If we subtract 156 from 161, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 39

Advancing to step 5:
If we divide 57 by 39, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 2041.0
Subtract 39 from 57 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 39

Advancing to step 6:
If we divide 184 by 39, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 20414.0
If we subtract 156 from 184, we get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 39

Moving on to step 7:
When dividing 283 by 39, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 204147.0
Subtract 273 from 283 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 39

Going ahead to step 8:
39 can be fit into 101 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 2041472.0
Deduct 78 from 101 and we're left with 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 9:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2041472.5
If we take 195 away from 230, we end up 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.

Moving on to step 10:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 2041472.58
If we take 312 away from 350, we end up 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.

Going ahead to step 11:
When dividing 380 by 39, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 2041472.589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
If we divide 290 by 39, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 2041472.5897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 2041472.58974
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
39 can be fit into 140 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 2041472.589743
If we subtract 117 from 140, 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.

Moving on to step 15:
39 goes into 230 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2041472.5897435
Deduct 195 from 230 and we're left 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.

Advancing to step 16:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 2041472.58974358
If we take 312 away from 350, we end up 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.

Our division results in 2041472.58974358 with a remaining 3.8e-08.
