We look at the division of 53780373 by 103 
Our goal is to divide 53780373 by 103.

On to step 1:
The number 103 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 103

Going ahead to step 2:
103 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 103

Advancing to step 3:
103 goes into 537 5 times with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 515 from 537 and we're left with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 103

Let's proceed to step 4:
When dividing 228 by 103, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 206 from 228, we get 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 103

On to step 5:
103 can be fit into 220 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 522.0
Subtract 206 from 220 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 103

Let's proceed to step 6:
When dividing 143 by 103, we get 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 5221.0
If we subtract 103 from 143, we get 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 103

Advancing to step 7:
103 can be fit into 407 3 times, resulting in a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 52213.0
Subtract 309 from 407 to get 98.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 103

Let's proceed to step 8:
983 divided by 103 is 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 522139.0
If we subtract 927 from 983, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
When dividing 560 by 103, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 522139.5
Subtracting 515 from 560 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
103 can be fit into 450 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 522139.54
If we take 412 away from 450, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
The number 103 fits into 380 3 times, leaving a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 522139.543
If we take 309 away from 380, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
103 goes into 710 6 times with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 522139.5436
Subtracting 618 from 710 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 13:
103 can be fit into 920 8 times, resulting in a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 522139.54368
Deduct 824 from 920 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
103 goes into 960 9 times with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 522139.543689
If we take 927 away from 960, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 15:
330 divided by 103 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 522139.5436893
The remainder is 21 after subtracting 309 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 16:
If we divide 210 by 103, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 522139.54368932
If we take 206 away from 210, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 522139.54368932, and the remainder is 4e-09.
