743877 divided by 35 
The aim is to understand the frequency of 35 in 743877.

Advancing to step 1:
35 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 35

Advancing to step 2:
When dividing 74 by 35, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 70 from 74, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 35

Going ahead to step 3:
When dividing 43 by 35, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 35 away from 43, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 35

Let's proceed to step 4:
The number 35 fits into 88 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 212.0
Subtracting 70 from 88 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 35

Going ahead to step 5:
35 goes into 187 5 times with a remainder of 12.
The next digit of our result is 5. 
Result so far: 2125.0
Subtracting 175 from 187 leaves us with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 35

Moving on to step 6:
If we divide 127 by 35, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 21253.0
Deduct 105 from 127 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.

On to step 7:
220 divided by 35 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 21253.6
If we subtract 210 from 220, we get 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 8:
35 goes into 100 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 21253.62
Deduct 70 from 100 and we're left 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.

Let's proceed to step 9:
If we divide 300 by 35, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 21253.628
Subtracting 280 from 300 leaves us 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.

On to step 10:
35 goes into 200 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 21253.6285
Subtract 175 from 200 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
35 can be fit into 250 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 21253.62857
If we take 245 away from 250, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 35, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 21253.628571
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 21253.6285714
Subtract 140 from 150 to get 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:
35 can be fit into 100 2 times, resulting in a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 21253.62857142
Subtracting 70 from 100 leaves us 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.

The final outcome is 21253.62857142, with a leftover of 3e-08.
