78237426 divided by 214 
The aim is to understand the frequency of 214 in 78237426.

On to step 1:
When dividing 7 by 214, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 214

Advancing to step 2:
214 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 214

Step 3:
The number 214 fits into 782 3 times, leaving a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 140 after subtracting 642 from 782.
Grab the next digit (3) from the dividend, add it to 140, then carry on: 1403 / 214

Let's proceed to step 4:
When dividing 1403 by 214, we get 6 with a remainder of 119.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 1284 away from 1403, we end up with 119.
Take the next digit (7) from the dividend and append it to 119, then repeat: 1197 / 214

Moving on to step 5:
If we divide 1197 by 214, we get 5 and a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 365.0
Subtract 1070 from 1197 to get 127.
Include the next digit (4) from the dividend after 127, then repeat: 1274 / 214

Step 6:
When dividing 1274 by 214, we get 5 with a remainder of 204.
Record the quotient 5 as the next digit in the result. 
Result so far: 3655.0
Subtract 1070 from 1274 to get 204.
Fetch the next digit (2) from the dividend, attach it to 204 and continue: 2042 / 214

Going ahead to step 7:
214 can be fit into 2042 9 times, resulting in a remainder of 116.
Write down 9 as next digit of the result. 
Result so far: 36559.0
If we subtract 1926 from 2042, we get 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 214

Advancing to step 8:
214 goes into 1166 5 times with a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 365595.0
The remainder is 96 after subtracting 1070 from 1166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 214 fits into 960 4 times, leaving a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 365595.4
Subtract 856 from 960 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
214 goes into 1040 4 times with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 365595.44
If we take 856 away from 1040, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

After the division, we end up with 365595.44 and a remainder of 0.184.
