70402972 ÷ 561 
The aim is to understand the frequency of 561 in 70402972.

Let's proceed to step 1:
The number 561 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 561

Let's proceed to step 2:
561 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 561

Advancing to step 3:
561 goes into 704 1 times with a remainder of 143.
The next digit of our result is 1. 
Result so far: 1.0
If we take 561 away from 704, we end up with 143.
Take the next digit (0) from the dividend and append it to 143, then repeat: 1430 / 561

Let's proceed to step 4:
If we divide 1430 by 561, we get 2 and a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 308 after subtracting 1122 from 1430.
Take the next digit (2) from the dividend and append it to 308, then repeat: 3082 / 561

On to step 5:
If we divide 3082 by 561, we get 5 and a remainder of 277.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtract 2805 from 3082 to get 277.
Fetch the next digit (9) from the dividend, attach it to 277 and continue: 2779 / 561

On to step 6:
2779 divided by 561 is 4 with a remainder of 535.
Write down 4 as next digit of the result. 
Result so far: 1254.0
If we subtract 2244 from 2779, we get 535.
Grab the next digit (7) from the dividend, add it to 535, then carry on: 5357 / 561

Going ahead to step 7:
When dividing 5357 by 561, we get 9 with a remainder of 308.
Put 9 as the next digit of the answer. 
Result so far: 12549.0
Deduct 5049 from 5357 and we're left with 308.
Append the next digit (2) from the dividend to 308 and continue with: 3082 / 561

Going ahead to step 8:
561 can be fit into 3082 5 times, resulting in a remainder of 277.
The next digit of our result is 5. 
Result so far: 125495.0
If we take 2805 away from 3082, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 9:
561 goes into 2770 4 times with a remainder of 526.
Write down 4 as next digit of the result. 
Result so far: 125495.4
If we take 2244 away from 2770, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 10:
561 can be fit into 5260 9 times, resulting in a remainder of 211.
Record the quotient 9 as the next digit in the result. 
Result so far: 125495.49
Subtract 5049 from 5260 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 11:
2110 divided by 561 is 3 with a remainder of 427.
Record the quotient 3 as the next digit in the result. 
Result so far: 125495.493
Subtracting 1683 from 2110 leaves us with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

On to step 12:
If we divide 4270 by 561, we get 7 and a remainder of 343.
The next digit of our result is 7. 
Result so far: 125495.4937
The remainder is 343 after subtracting 3927 from 4270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 13:
561 goes into 3430 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 125495.49376
If we take 3366 away from 3430, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
If we divide 640 by 561, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 125495.493761
Deduct 561 from 640 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 15:
When dividing 790 by 561, we get 1 with a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 125495.4937611
Subtracting 561 from 790 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Our division results in 125495.4937611 with a remaining 2.29e-06.
