974414 ÷ 78 
Our goal is to divide 974414 by 78.

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
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 78

On to step 2:
When dividing 97 by 78, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 78 from 97 and we're left with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 78

Moving on to step 3:
194 divided by 78 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 156 from 194 leaves us with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 78

Step 4:
When dividing 384 by 78, we get 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we subtract 312 from 384, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 78

Let's proceed to step 5:
78 goes into 721 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
Deduct 702 from 721 and we're left with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 78

Let's proceed to step 6:
194 divided by 78 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 12492.0
The remainder is 38 after subtracting 156 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 12492.4
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
78 goes into 680 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 12492.48
If we subtract 624 from 680, 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.

Moving on to step 9:
If we divide 560 by 78, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 12492.487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
When dividing 140 by 78, we get 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 12492.4871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
If we divide 620 by 78, we get 7 and a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 12492.48717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 12492.487179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 12492.4871794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 12492.48717948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 12492.48717948 with a remainder of 5.6e-08.
