78763621 ÷ 67 
The aim is to understand the frequency of 67 in 78763621.

On to step 1:
If we divide 7 by 67, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 67

On to step 2:
78 divided by 67 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 67 from 78 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 67

Moving on to step 3:
67 goes into 117 1 times with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 67 from 117 to get 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 67

On to step 4:
67 goes into 506 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtracting 469 from 506 leaves us with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 67

On to step 5:
When dividing 373 by 67, we get 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
Subtracting 335 from 373 leaves us with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 67

Going ahead to step 6:
67 goes into 386 5 times with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 11755.0
Deduct 335 from 386 and we're left with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 67

On to step 7:
67 goes into 512 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 117557.0
Deduct 469 from 512 and we're left with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 67

Step 8:
When dividing 431 by 67, we get 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 1175576.0
Deduct 402 from 431 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
67 can be fit into 290 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 1175576.4
Deduct 268 from 290 and we're left with 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 10:
If we divide 220 by 67, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 1175576.43
Deduct 201 from 220 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
The number 67 fits into 190 2 times, leaving a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 1175576.432
Subtracting 134 from 190 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.

Step 12:
67 goes into 560 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1175576.4328
Deduct 536 from 560 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
240 divided by 67 is 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 1175576.43283
Deduct 201 from 240 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 14:
67 can be fit into 390 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 1175576.432835
Deduct 335 from 390 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 15:
When dividing 550 by 67, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1175576.4328358
Subtracting 536 from 550 leaves us 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.

Let's proceed to step 16:
The number 67 fits into 140 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1175576.43283582
Subtract 134 from 140 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 1175576.43283582 with a remaining 6e-09.
