We divide 88232621 by 661
The aim is to understand the frequency of 661 in 88232621.

Going ahead to step 1:
661 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 661

On to step 2:
The number 661 fits into 88 0 times, leaving a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 661

Moving on to step 3:
882 divided by 661 is 1 with a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 661 away from 882, we end up with 221.
Include the next digit (3) from the dividend after 221, then repeat: 2213 / 661

Going ahead to step 4:
The number 661 fits into 2213 3 times, leaving a remainder of 230.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1983 away from 2213, we end up with 230.
Append the next digit (2) from the dividend to 230 and continue with: 2302 / 661

Going ahead to step 5:
661 goes into 2302 3 times with a remainder of 319.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtract 1983 from 2302 to get 319.
Take the next digit (6) from the dividend and append it to 319, then repeat: 3196 / 661

Advancing to step 6:
When dividing 3196 by 661, we get 4 with a remainder of 552.
Use 4 as the next digit of our solution. 
Result so far: 1334.0
Subtract 2644 from 3196 to get 552.
Grab the next digit (2) from the dividend, add it to 552, then carry on: 5522 / 661

Let's proceed to step 7:
When dividing 5522 by 661, we get 8 with a remainder of 234.
Write down 8 as next digit of the result. 
Result so far: 13348.0
Deduct 5288 from 5522 and we're left with 234.
Take the next digit (1) from the dividend and append it to 234, then repeat: 2341 / 661

Step 8:
661 can be fit into 2341 3 times, resulting in a remainder of 358.
Write down 3 as next digit of the result. 
Result so far: 133483.0
If we subtract 1983 from 2341, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 9:
The number 661 fits into 3580 5 times, leaving a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 133483.5
Deduct 3305 from 3580 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 10:
If we divide 2750 by 661, we get 4 and a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 133483.54
If we take 2644 away from 2750, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
The number 661 fits into 1060 1 times, leaving a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 133483.541
If we take 661 away from 1060, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Going ahead to step 12:
3990 divided by 661 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 133483.5416
Subtracting 3966 from 3990 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
If we divide 240 by 661, we get 0 and a remainder of 240.
The next digit of our result is 0. 
Result so far: 133483.5416
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
When dividing 2400 by 661, we get 3 with a remainder of 417.
Use 3 as the next digit of our solution. 
Result so far: 133483.541603
Deduct 1983 from 2400 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 15:
4170 divided by 661 is 6 with a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 133483.5416036
The remainder is 204 after subtracting 3966 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 16:
The number 661 fits into 2040 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 133483.54160363
If we take 1983 away from 2040, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The quotient of the division is 133483.54160363, and the remainder is 5.7e-08.
