743387 ÷ 70 
The aim is to understand the frequency of 70 in 743387.

Moving on to step 1:
When dividing 7 by 70, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 70

Going ahead to step 2:
The number 70 fits into 74 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 70 from 74, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 70

Advancing to step 3:
70 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 43 to get 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 70

Advancing to step 4:
433 divided by 70 is 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 13 after subtracting 420 from 433.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 70

Going ahead to step 5:
If we divide 138 by 70, we get 1 and a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 1061.0
Subtracting 70 from 138 leaves us with 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 70

Moving on to step 6:
If we divide 687 by 70, we get 9 and a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 10619.0
If we subtract 630 from 687, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
When dividing 570 by 70, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 10619.8
Deduct 560 from 570 and we're left 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.

Going ahead to step 8:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 10619.81
The remainder is 30 after subtracting 70 from 100.
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 9:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 10619.814
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 10:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 10619.8142
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.

Moving on to step 11:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 10619.81428
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.

Let's proceed to step 12:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10619.814285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 10619.8142857
Deduct 490 from 500 and we're left 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.

Moving on to step 14:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 10619.81428571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 10619.81428571 with a remaining 3e-08.
