We look at the division of 84767710 by 661 
The aim is to understand the frequency of 661 in 84767710.

Let's proceed to step 1:
8 divided by 661 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 661

On to step 2:
When dividing 84 by 661, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 661

Advancing to step 3:
847 divided by 661 is 1 with a remainder of 186.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 661 from 847, we get 186.
Bring next digit (6) of the dividend behind the 186 and repeat the process: 1866 / 661

Moving on to step 4:
If we divide 1866 by 661, we get 2 and a remainder of 544.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1322 from 1866 and we're left with 544.
Take the next digit (7) from the dividend and append it to 544, then repeat: 5447 / 661

Advancing to step 5:
661 can be fit into 5447 8 times, resulting in a remainder of 159.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 5288 from 5447 to get 159.
Fetch the next digit (7) from the dividend, attach it to 159 and continue: 1597 / 661

On to step 6:
661 goes into 1597 2 times with a remainder of 275.
Write down 2 as next digit of the result. 
Result so far: 1282.0
Subtract 1322 from 1597 to get 275.
Fetch the next digit (1) from the dividend, attach it to 275 and continue: 2751 / 661

On to step 7:
661 goes into 2751 4 times with a remainder of 107.
Put 4 as the next digit of the answer. 
Result so far: 12824.0
Subtracting 2644 from 2751 leaves us with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 661

Moving on to step 8:
When dividing 1070 by 661, we get 1 with a remainder of 409.
Record the quotient 1 as the next digit in the result. 
Result so far: 128241.0
Subtracting 661 from 1070 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 9:
4090 divided by 661 is 6 with a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 128241.6
Deduct 3966 from 4090 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
661 goes into 1240 1 times with a remainder of 579.
Put 1 as the next digit of the answer. 
Result so far: 128241.61
Subtract 661 from 1240 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 11:
If we divide 5790 by 661, we get 8 and a remainder of 502.
The next digit of our result is 8. 
Result so far: 128241.618
The remainder is 502 after subtracting 5288 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 12:
661 goes into 5020 7 times with a remainder of 393.
Record the quotient 7 as the next digit in the result. 
Result so far: 128241.6187
The remainder is 393 after subtracting 4627 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 13:
The number 661 fits into 3930 5 times, leaving a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 128241.61875
The remainder is 625 after subtracting 3305 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 14:
The number 661 fits into 6250 9 times, leaving a remainder of 301.
Record the quotient 9 as the next digit in the result. 
Result so far: 128241.618759
The remainder is 301 after subtracting 5949 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 15:
661 can be fit into 3010 4 times, resulting in a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 128241.6187594
The remainder is 366 after subtracting 2644 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 16:
661 goes into 3660 5 times with a remainder of 355.
The number 5 becomes the next digit in our result. 
Result so far: 128241.61875945
If we subtract 3305 from 3660, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The quotient of the division is 128241.61875945, and the remainder is 3.55e-07.
