We divide 61669087 by 657
The aim is to understand the frequency of 657 in 61669087.

Advancing to step 1:
657 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 657

Advancing to step 2:
If we divide 61 by 657, we get 0 and a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Bring next digit (6) of the dividend behind the 61 and repeat the process: 616 / 657

On to step 3:
When dividing 616 by 657, we get 0 with a remainder of 616.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 616, we get 616.
Append the next digit (6) from the dividend to 616 and continue with: 6166 / 657

Let's proceed to step 4:
6166 divided by 657 is 9 with a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5913 from 6166, we get 253.
Grab the next digit (9) from the dividend, add it to 253, then carry on: 2539 / 657

Going ahead to step 5:
2539 divided by 657 is 3 with a remainder of 568.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 1971 from 2539 leaves us with 568.
Bring next digit (0) of the dividend behind the 568 and repeat the process: 5680 / 657

Advancing to step 6:
657 can be fit into 5680 8 times, resulting in a remainder of 424.
The next digit of our result is 8. 
Result so far: 938.0
Subtract 5256 from 5680 to get 424.
Grab the next digit (8) from the dividend, add it to 424, then carry on: 4248 / 657

Moving on to step 7:
The number 657 fits into 4248 6 times, leaving a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 9386.0
The remainder is 306 after subtracting 3942 from 4248.
Append the next digit (7) from the dividend to 306 and continue with: 3067 / 657

On to step 8:
3067 divided by 657 is 4 with a remainder of 439.
Put 4 as the next digit of the answer. 
Result so far: 93864.0
If we subtract 2628 from 3067, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 9:
657 goes into 4390 6 times with a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 93864.6
Deduct 3942 from 4390 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 10:
4480 divided by 657 is 6 with a remainder of 538.
Write down 6 as next digit of the result. 
Result so far: 93864.66
If we subtract 3942 from 4480, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The final outcome is 93864.66, with a leftover of 0.538.
