We divide 64990582 by 869
The aim is to understand the frequency of 869 in 64990582.

On to step 1:
When dividing 6 by 869, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 869

On to step 2:
When dividing 64 by 869, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 869

Going ahead to step 3:
869 can be fit into 649 0 times, resulting in a remainder of 649.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 649 to get 649.
Grab the next digit (9) from the dividend, add it to 649, then carry on: 6499 / 869

Let's proceed to step 4:
869 can be fit into 6499 7 times, resulting in a remainder of 416.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6083 from 6499, we get 416.
Grab the next digit (0) from the dividend, add it to 416, then carry on: 4160 / 869

Advancing to step 5:
869 goes into 4160 4 times with a remainder of 684.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 3476 from 4160 leaves us with 684.
Grab the next digit (5) from the dividend, add it to 684, then carry on: 6845 / 869

Going ahead to step 6:
When dividing 6845 by 869, we get 7 with a remainder of 762.
Write down 7 as next digit of the result. 
Result so far: 747.0
Subtracting 6083 from 6845 leaves us with 762.
Bring next digit (8) of the dividend behind the 762 and repeat the process: 7628 / 869

On to step 7:
869 can be fit into 7628 8 times, resulting in a remainder of 676.
Record the quotient 8 as the next digit in the result. 
Result so far: 7478.0
Deduct 6952 from 7628 and we're left with 676.
Bring next digit (2) of the dividend behind the 676 and repeat the process: 6762 / 869

Let's proceed to step 8:
869 can be fit into 6762 7 times, resulting in a remainder of 679.
The number 7 becomes the next digit in our result. 
Result so far: 74787.0
If we take 6083 away from 6762, we end up with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Moving on to step 9:
When dividing 6790 by 869, we get 7 with a remainder of 707.
Record the quotient 7 as the next digit in the result. 
Result so far: 74787.7
Subtracting 6083 from 6790 leaves us with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Going ahead to step 10:
When dividing 7070 by 869, we get 8 with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 74787.78
Subtract 6952 from 7070 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 11:
If we divide 1180 by 869, we get 1 and a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 74787.781
The remainder is 311 after subtracting 869 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 12:
869 can be fit into 3110 3 times, resulting in a remainder of 503.
The next digit of our result is 3. 
Result so far: 74787.7813
Subtracting 2607 from 3110 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Going ahead to step 13:
If we divide 5030 by 869, we get 5 and a remainder of 685.
Record the quotient 5 as the next digit in the result. 
Result so far: 74787.78135
Subtracting 4345 from 5030 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 14:
869 can be fit into 6850 7 times, resulting in a remainder of 767.
Put 7 as the next digit of the answer. 
Result so far: 74787.781357
If we take 6083 away from 6850, we end up with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Step 15:
869 can be fit into 7670 8 times, resulting in a remainder of 718.
Use 8 as the next digit of our solution. 
Result so far: 74787.7813578
Deduct 6952 from 7670 and we're left with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Advancing to step 16:
869 goes into 7180 8 times with a remainder of 228.
Record the quotient 8 as the next digit in the result. 
Result so far: 74787.78135788
Deduct 6952 from 7180 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Our division results in 74787.78135788 with a remaining 2.28e-07.
