71361603 divided by 70 
The aim is to understand the frequency of 70 in 71361603.

Going ahead to step 1:
7 divided by 70 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 70

Moving on to step 2:
If we divide 71 by 70, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 70 from 71, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 70

Let's proceed to step 3:
The number 70 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 70

Let's proceed to step 4:
70 goes into 136 1 times with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 70 from 136 to get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 70

Advancing to step 5:
If we divide 661 by 70, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 1019.0
If we take 630 away from 661, we end up with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 70

Moving on to step 6:
316 divided by 70 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 10194.0
Subtracting 280 from 316 leaves us with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 70

Let's proceed to step 7:
70 can be fit into 360 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 101945.0
Subtracting 350 from 360 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 70

On to step 8:
When dividing 103 by 70, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1019451.0
Subtracting 70 from 103 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
70 can be fit into 330 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 1019451.4
Subtract 280 from 330 to 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.

Step 10:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1019451.47
If we subtract 490 from 500, 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.

Advancing to step 11:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1019451.471
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.

Going ahead to step 12:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1019451.4714
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.

Let's proceed to step 13:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 1019451.47142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 1019451.471428
Deduct 560 from 600 and we're left 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.

Moving on to step 15:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1019451.4714285
Subtract 350 from 400 to 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.

Going ahead to step 16:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1019451.47142857
If we take 490 away from 500, we end up 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.

Our division results in 1019451.47142857 with a remaining 1e-08.
