We look at the division of 61671645 by 583 
The aim is to understand the frequency of 583 in 61671645.

Moving on to step 1:
583 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 583

Going ahead to step 2:
583 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 583

Step 3:
583 can be fit into 616 1 times, resulting in a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 583 from 616, we get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 583

Moving on to step 4:
337 divided by 583 is 0 with a remainder of 337.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 337, we get 337.
Grab the next digit (1) from the dividend, add it to 337, then carry on: 3371 / 583

Going ahead to step 5:
The number 583 fits into 3371 5 times, leaving a remainder of 456.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we take 2915 away from 3371, we end up with 456.
Include the next digit (6) from the dividend after 456, then repeat: 4566 / 583

Let's proceed to step 6:
The number 583 fits into 4566 7 times, leaving a remainder of 485.
Use 7 as the next digit of our solution. 
Result so far: 1057.0
If we take 4081 away from 4566, we end up with 485.
Bring next digit (4) of the dividend behind the 485 and repeat the process: 4854 / 583

Step 7:
4854 divided by 583 is 8 with a remainder of 190.
The number 8 becomes the next digit in our result. 
Result so far: 10578.0
The remainder is 190 after subtracting 4664 from 4854.
Bring next digit (5) of the dividend behind the 190 and repeat the process: 1905 / 583

Advancing to step 8:
583 can be fit into 1905 3 times, resulting in a remainder of 156.
Record the quotient 3 as the next digit in the result. 
Result so far: 105783.0
Subtracting 1749 from 1905 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 9:
When dividing 1560 by 583, we get 2 with a remainder of 394.
Write down 2 as next digit of the result. 
Result so far: 105783.2
If we subtract 1166 from 1560, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 10:
If we divide 3940 by 583, we get 6 and a remainder of 442.
Put 6 as the next digit of the answer. 
Result so far: 105783.26
If we subtract 3498 from 3940, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 11:
4420 divided by 583 is 7 with a remainder of 339.
Put 7 as the next digit of the answer. 
Result so far: 105783.267
The remainder is 339 after subtracting 4081 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 12:
When dividing 3390 by 583, we get 5 with a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 105783.2675
If we subtract 2915 from 3390, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 13:
When dividing 4750 by 583, we get 8 with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 105783.26758
Subtract 4664 from 4750 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 14:
860 divided by 583 is 1 with a remainder of 277.
The number 1 becomes the next digit in our result. 
Result so far: 105783.267581
If we subtract 583 from 860, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 15:
583 goes into 2770 4 times with a remainder of 438.
The next digit of our result is 4. 
Result so far: 105783.2675814
If we take 2332 away from 2770, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 16:
4380 divided by 583 is 7 with a remainder of 299.
Write down 7 as next digit of the result. 
Result so far: 105783.26758147
The remainder is 299 after subtracting 4081 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

The quotient of the division is 105783.26758147, and the remainder is 2.99e-07.
