Let's divide 938401 by 78
Let's see how many times 78 fits into 938401.

Going ahead to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 78

Moving on to step 2:
78 can be fit into 93 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 93 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 78

Advancing to step 3:
78 can be fit into 158 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 156 from 158, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 78

Step 4:
78 goes into 24 0 times with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 78

Moving on to step 5:
If we divide 240 by 78, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1203.0
The remainder is 6 after subtracting 234 from 240.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 78

Let's proceed to step 6:
78 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 12030.0
If we take 0 away from 61, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
78 goes into 610 7 times with a remainder of 64.
The next digit of our result is 7. 
Result so far: 12030.7
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12030.78
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 78, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 12030.782
Deduct 156 from 160 and we're left 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.

Moving on to step 10:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12030.782
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
78 goes into 400 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 12030.78205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 78, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 12030.782051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
78 goes into 220 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 12030.7820512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
If we divide 640 by 78, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12030.78205128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 12030.78205128 and a remainder of 1.6e-08.
