398955 ÷ 76 
Let's see how many times 76 fits into 398955.

Step 1:
The number 76 fits into 3 0 times, leaving 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.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 76

Advancing to step 2:
The number 76 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 76

On to step 3:
398 divided by 76 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 380 from 398 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 76

Step 4:
The number 76 fits into 189 2 times, leaving a remainder of 37.
The next digit of our result is 2. 
Result so far: 52.0
If we take 152 away from 189, we end up with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 76

Moving on to step 5:
76 can be fit into 375 4 times, resulting in a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 524.0
The remainder is 71 after subtracting 304 from 375.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 76

On to step 6:
76 goes into 715 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 5249.0
Subtract 684 from 715 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
76 can be fit into 310 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 5249.4
Subtracting 304 from 310 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 76 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 5249.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 76 fits into 600 7 times, leaving a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 5249.407
If we subtract 532 from 600, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
76 goes into 680 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 5249.4078
Subtract 608 from 680 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
If we divide 720 by 76, we get 9 and a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 5249.40789
The remainder is 36 after subtracting 684 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
76 goes into 360 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 5249.407894
If we take 304 away from 360, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
560 divided by 76 is 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 5249.4078947
If we subtract 532 from 560, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
When dividing 280 by 76, we get 3 with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 5249.40789473
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 5249.40789473 and a remainder of 5.2e-08.
