We're dividing 53865940 by 373 
Let's see how many times 373 fits into 53865940.

On to step 1:
If we divide 5 by 373, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 373

Moving on to step 2:
The number 373 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 373

Going ahead to step 3:
373 goes into 538 1 times with a remainder of 165.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 373 from 538 leaves us with 165.
Bring next digit (6) of the dividend behind the 165 and repeat the process: 1656 / 373

Step 4:
When dividing 1656 by 373, we get 4 with a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1492 from 1656 and we're left with 164.
Bring next digit (5) of the dividend behind the 164 and repeat the process: 1645 / 373

Moving on to step 5:
373 can be fit into 1645 4 times, resulting in a remainder of 153.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we take 1492 away from 1645, we end up with 153.
Bring next digit (9) of the dividend behind the 153 and repeat the process: 1539 / 373

On to step 6:
373 can be fit into 1539 4 times, resulting in a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 1444.0
The remainder is 47 after subtracting 1492 from 1539.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 373

Step 7:
373 can be fit into 474 1 times, resulting in a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 14441.0
Deduct 373 from 474 and we're left with 101.
Include the next digit (0) from the dividend after 101, then repeat: 1010 / 373

Advancing to step 8:
1010 divided by 373 is 2 with a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 144412.0
The remainder is 264 after subtracting 746 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 9:
When dividing 2640 by 373, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 144412.7
Deduct 2611 from 2640 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
If we divide 290 by 373, we get 0 and a remainder of 290.
The next digit of our result is 0. 
Result so far: 144412.7
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 11:
If we divide 2900 by 373, we get 7 and a remainder of 289.
The number 7 becomes the next digit in our result. 
Result so far: 144412.707
Subtract 2611 from 2900 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 12:
When dividing 2890 by 373, we get 7 with a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 144412.7077
The remainder is 279 after subtracting 2611 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

After the division, we end up with 144412.7077 and a remainder of 0.00279.
