We're dividing 377830 by 86 
We're looking to find how many times 86 goes into 377830.

Going ahead to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 86

Going ahead to step 2:
37 divided by 86 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 86

Moving on to step 3:
When dividing 377 by 86, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 344 away from 377, we end up with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 86

Going ahead to step 4:
The number 86 fits into 338 3 times, leaving a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 258 from 338, we get 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 86

Step 5:
803 divided by 86 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 439.0
The remainder is 29 after subtracting 774 from 803.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 86

Let's proceed to step 6:
290 divided by 86 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 4393.0
Deduct 258 from 290 and we're left 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.

Going ahead to step 7:
86 goes into 320 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 4393.3
Subtracting 258 from 320 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.

Let's proceed to step 8:
The number 86 fits into 620 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 4393.37
Subtracting 602 from 620 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
When dividing 180 by 86, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4393.372
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
If we divide 80 by 86, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4393.372
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
If we divide 800 by 86, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 4393.37209
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
260 divided by 86 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 4393.372093
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
If we divide 20 by 86, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 4393.372093
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
86 goes into 200 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 4393.37209302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 4393.37209302, with a leftover of 2.8e-08.
