437675 divided by 78 
The aim is to understand the frequency of 78 in 437675.

Let's proceed to step 1:
4 divided by 78 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 78

Going ahead to step 2:
If we divide 43 by 78, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 78

Step 3:
78 can be fit into 437 5 times, resulting in a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 390 away from 437, we end up with 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 78

Moving on to step 4:
If we divide 476 by 78, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Subtracting 468 from 476 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 78

Step 5:
78 can be fit into 87 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 561.0
If we subtract 78 from 87, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 78

Advancing to step 6:
78 goes into 95 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 5611.0
Subtracting 78 from 95 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
78 can be fit into 170 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 5611.2
If we take 156 away from 170, 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.

On to step 8:
If we divide 140 by 78, we get 1 and a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 5611.21
Subtract 78 from 140 to get 62.
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 9:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 5611.217
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 5611.2179
Subtracting 702 from 740 leaves us 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:
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: 5611.21794
Deduct 312 from 380 and we're left 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 12:
78 can be fit into 680 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 5611.217948
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.

Let's proceed to step 13:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 5611.2179487
Subtract 546 from 560 to get 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 14:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 5611.21794871
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.

Our division results in 5611.21794871 with a remaining 6.2e-08.
