We look at the division of 61226946 by 687 
The aim is to understand the frequency of 687 in 61226946.

Going ahead to step 1:
The number 687 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 687

Let's proceed to step 2:
When dividing 61 by 687, we get 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 687

Let's proceed to step 3:
The number 687 fits into 612 0 times, leaving a remainder of 612.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 612 leaves us with 612.
Grab the next digit (2) from the dividend, add it to 612, then carry on: 6122 / 687

Moving on to step 4:
6122 divided by 687 is 8 with a remainder of 626.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 5496 from 6122 and we're left with 626.
Bring next digit (6) of the dividend behind the 626 and repeat the process: 6266 / 687

On to step 5:
6266 divided by 687 is 9 with a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtract 6183 from 6266 to get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 687

Moving on to step 6:
687 goes into 839 1 times with a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 891.0
If we subtract 687 from 839, we get 152.
Fetch the next digit (4) from the dividend, attach it to 152 and continue: 1524 / 687

Going ahead to step 7:
687 can be fit into 1524 2 times, resulting in a remainder of 150.
The next digit of our result is 2. 
Result so far: 8912.0
Deduct 1374 from 1524 and we're left with 150.
Fetch the next digit (6) from the dividend, attach it to 150 and continue: 1506 / 687

Advancing to step 8:
The number 687 fits into 1506 2 times, leaving a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 89122.0
The remainder is 132 after subtracting 1374 from 1506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
If we divide 1320 by 687, we get 1 and a remainder of 633.
Use 1 as the next digit of our solution. 
Result so far: 89122.1
Deduct 687 from 1320 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 10:
If we divide 6330 by 687, we get 9 and a remainder of 147.
The number 9 becomes the next digit in our result. 
Result so far: 89122.19
Subtract 6183 from 6330 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 11:
687 can be fit into 1470 2 times, resulting in a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 89122.192
Subtract 1374 from 1470 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
The number 687 fits into 960 1 times, leaving a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 89122.1921
If we take 687 away from 960, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 13:
If we divide 2730 by 687, we get 3 and a remainder of 669.
Put 3 as the next digit of the answer. 
Result so far: 89122.19213
Subtracting 2061 from 2730 leaves us with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Moving on to step 14:
687 can be fit into 6690 9 times, resulting in a remainder of 507.
Use 9 as the next digit of our solution. 
Result so far: 89122.192139
Subtracting 6183 from 6690 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 15:
The number 687 fits into 5070 7 times, leaving a remainder of 261.
The next digit of our result is 7. 
Result so far: 89122.1921397
Subtract 4809 from 5070 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 16:
2610 divided by 687 is 3 with a remainder of 549.
Record the quotient 3 as the next digit in the result. 
Result so far: 89122.19213973
If we subtract 2061 from 2610, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

The final result is 89122.19213973 with a remainder of 5.49e-07.
