772138 ÷ 70 
The aim is to understand the frequency of 70 in 772138.

Let's proceed to step 1:
If we divide 7 by 70, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 70

On to step 2:
When dividing 77 by 70, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 7 after subtracting 70 from 77.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 70

Moving on to step 3:
70 goes into 72 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 70 from 72 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 70

On to step 4:
The number 70 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 21, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 70

Advancing to step 5:
213 divided by 70 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1103.0
Subtract 210 from 213 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 70

Let's proceed to step 6:
The number 70 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 11030.0
If we subtract 0 from 38, 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.

Advancing to step 7:
The number 70 fits into 380 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11030.5
If we take 350 away from 380, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 70, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 11030.54
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 11030.542
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 11030.5428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11030.54285
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
500 divided by 70 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 11030.542857
Subtracting 490 from 500 leaves us 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.

On to step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 11030.5428571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11030.54285714
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 11030.54285714 with a balance of 2e-08.
