We're dividing 57140144 by 397 
We want to figure out the number of times 57140144 can be divided by 397.

Going ahead to step 1:
If we divide 5 by 397, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 397

Going ahead to step 2:
397 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 397

On to step 3:
The number 397 fits into 571 1 times, leaving a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 397 away from 571, we end up with 174.
Fetch the next digit (4) from the dividend, attach it to 174 and continue: 1744 / 397

Moving on to step 4:
The number 397 fits into 1744 4 times, leaving a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1588 from 1744 leaves us with 156.
Take the next digit (0) from the dividend and append it to 156, then repeat: 1560 / 397

Let's proceed to step 5:
397 goes into 1560 3 times with a remainder of 369.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtract 1191 from 1560 to get 369.
Fetch the next digit (1) from the dividend, attach it to 369 and continue: 3691 / 397

Going ahead to step 6:
3691 divided by 397 is 9 with a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 1439.0
If we take 3573 away from 3691, we end up with 118.
Grab the next digit (4) from the dividend, add it to 118, then carry on: 1184 / 397

Step 7:
397 goes into 1184 2 times with a remainder of 390.
Write down 2 as next digit of the result. 
Result so far: 14392.0
The remainder is 390 after subtracting 794 from 1184.
Append the next digit (4) from the dividend to 390 and continue with: 3904 / 397

Going ahead to step 8:
When dividing 3904 by 397, we get 9 with a remainder of 331.
Use 9 as the next digit of our solution. 
Result so far: 143929.0
Subtract 3573 from 3904 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
The number 397 fits into 3310 8 times, leaving a remainder of 134.
Use 8 as the next digit of our solution. 
Result so far: 143929.8
Deduct 3176 from 3310 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
397 can be fit into 1340 3 times, resulting in a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 143929.83
If we take 1191 away from 1340, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 11:
The number 397 fits into 1490 3 times, leaving a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 143929.833
If we subtract 1191 from 1490, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

The final outcome is 143929.833, with a leftover of 0.0299.
