We look at the division of 7291257 by 378 
Our goal is to divide 7291257 by 378.

Moving on to step 1:
The number 378 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 378

Advancing to step 2:
378 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 378

On to step 3:
378 can be fit into 729 1 times, resulting in a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 378 from 729 and we're left with 351.
Fetch the next digit (1) from the dividend, attach it to 351 and continue: 3511 / 378

Let's proceed to step 4:
When dividing 3511 by 378, we get 9 with a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3402 from 3511 to get 109.
Fetch the next digit (2) from the dividend, attach it to 109 and continue: 1092 / 378

Moving on to step 5:
378 goes into 1092 2 times with a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 192.0
Subtracting 756 from 1092 leaves us with 336.
Fetch the next digit (5) from the dividend, attach it to 336 and continue: 3365 / 378

Moving on to step 6:
378 can be fit into 3365 8 times, resulting in a remainder of 341.
Put 8 as the next digit of the answer. 
Result so far: 1928.0
The remainder is 341 after subtracting 3024 from 3365.
Append the next digit (7) from the dividend to 341 and continue with: 3417 / 378

Moving on to step 7:
3417 divided by 378 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 19289.0
Deduct 3402 from 3417 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
378 goes into 150 0 times with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 19289.0
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
378 can be fit into 1500 3 times, resulting in a remainder of 366.
Use 3 as the next digit of our solution. 
Result so far: 19289.03
The remainder is 366 after subtracting 1134 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 10:
If we divide 3660 by 378, we get 9 and a remainder of 258.
Put 9 as the next digit of the answer. 
Result so far: 19289.039
Subtract 3402 from 3660 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 11:
2580 divided by 378 is 6 with a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 19289.0396
Deduct 2268 from 2580 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
The number 378 fits into 3120 8 times, leaving a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 19289.03968
The remainder is 96 after subtracting 3024 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
378 goes into 960 2 times with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 19289.039682
Subtract 756 from 960 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 14:
2040 divided by 378 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 19289.0396825
If we subtract 1890 from 2040, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
When dividing 1500 by 378, we get 3 with a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 19289.03968253
Subtracting 1134 from 1500 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Our division results in 19289.03968253 with a remaining 3.66e-07.
