We look at the division of 3953874 by 189 
Our goal is to divide 3953874 by 189.

Step 1:
189 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 189

On to step 2:
189 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 189

On to step 3:
The number 189 fits into 395 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 378 from 395 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 189

Step 4:
173 divided by 189 is 0 with a remainder of 173.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 173 after subtracting 0 from 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 189

Step 5:
1738 divided by 189 is 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we subtract 1701 from 1738, we get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 189

Advancing to step 6:
189 can be fit into 377 1 times, resulting in a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 2091.0
Subtracting 189 from 377 leaves us with 188.
Append the next digit (4) from the dividend to 188 and continue with: 1884 / 189

Going ahead to step 7:
1884 divided by 189 is 9 with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 20919.0
If we take 1701 away from 1884, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 8:
If we divide 1830 by 189, we get 9 and a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 20919.9
If we take 1701 away from 1830, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
1290 divided by 189 is 6 with a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 20919.96
Subtracting 1134 from 1290 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 10:
189 goes into 1560 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 20919.968
Deduct 1512 from 1560 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.

Let's proceed to step 11:
When dividing 480 by 189, we get 2 with a remainder of 102.
The next digit of our result is 2. 
Result so far: 20919.9682
If we take 378 away from 480, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 12:
1020 divided by 189 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 20919.96825
Subtract 945 from 1020 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
When dividing 750 by 189, we get 3 with a remainder of 183.
The next digit of our result is 3. 
Result so far: 20919.968253
If we take 567 away from 750, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 14:
If we divide 1830 by 189, we get 9 and a remainder of 129.
The next digit of our result is 9. 
Result so far: 20919.9682539
The remainder is 129 after subtracting 1701 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 15:
If we divide 1290 by 189, we get 6 and a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 20919.96825396
If we take 1134 away from 1290, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

In conclusion, the division gives 20919.96825396 with a balance of 1.56e-07.
