Let's divide 397440 by 236
Our goal is to divide 397440 by 236.

Step 1:
If we divide 3 by 236, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 236

Step 2:
If we divide 39 by 236, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 236

Advancing to step 3:
397 divided by 236 is 1 with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 236 from 397, we get 161.
Bring next digit (4) of the dividend behind the 161 and repeat the process: 1614 / 236

Advancing to step 4:
The number 236 fits into 1614 6 times, leaving a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 1416 from 1614 and we're left with 198.
Grab the next digit (4) from the dividend, add it to 198, then carry on: 1984 / 236

Step 5:
236 goes into 1984 8 times with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we take 1888 away from 1984, we end up with 96.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 236

Moving on to step 6:
960 divided by 236 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1684.0
If we take 944 away from 960, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 236, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 1684.0
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 8:
1600 divided by 236 is 6 with a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 1684.06
Subtract 1416 from 1600 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
If we divide 1840 by 236, we get 7 and a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 1684.067
Subtracting 1652 from 1840 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 10:
If we divide 1880 by 236, we get 7 and a remainder of 228.
The next digit of our result is 7. 
Result so far: 1684.0677
If we take 1652 away from 1880, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 1684.0677 with a remainder of 0.00228.
