86863477 ÷ 674 
The aim is to understand the frequency of 674 in 86863477.

Let's proceed to step 1:
The number 674 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 674

On to step 2:
674 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 674

Moving on to step 3:
When dividing 868 by 674, we get 1 with a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 194 after subtracting 674 from 868.
Append the next digit (6) from the dividend to 194 and continue with: 1946 / 674

Moving on to step 4:
674 can be fit into 1946 2 times, resulting in a remainder of 598.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1348 away from 1946, we end up with 598.
Grab the next digit (3) from the dividend, add it to 598, then carry on: 5983 / 674

Step 5:
674 can be fit into 5983 8 times, resulting in a remainder of 591.
The next digit of our result is 8. 
Result so far: 128.0
If we take 5392 away from 5983, we end up with 591.
Bring next digit (4) of the dividend behind the 591 and repeat the process: 5914 / 674

On to step 6:
674 can be fit into 5914 8 times, resulting in a remainder of 522.
Put 8 as the next digit of the answer. 
Result so far: 1288.0
Subtracting 5392 from 5914 leaves us with 522.
Bring next digit (7) of the dividend behind the 522 and repeat the process: 5227 / 674

Advancing to step 7:
674 can be fit into 5227 7 times, resulting in a remainder of 509.
Use 7 as the next digit of our solution. 
Result so far: 12887.0
Subtract 4718 from 5227 to get 509.
Grab the next digit (7) from the dividend, add it to 509, then carry on: 5097 / 674

Advancing to step 8:
674 goes into 5097 7 times with a remainder of 379.
Write down 7 as next digit of the result. 
Result so far: 128877.0
Subtracting 4718 from 5097 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 9:
3790 divided by 674 is 5 with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 128877.5
The remainder is 420 after subtracting 3370 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
4200 divided by 674 is 6 with a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 128877.56
Subtracting 4044 from 4200 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
If we divide 1560 by 674, we get 2 and a remainder of 212.
The next digit of our result is 2. 
Result so far: 128877.562
The remainder is 212 after subtracting 1348 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 12:
674 goes into 2120 3 times with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 128877.5623
Subtract 2022 from 2120 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 13:
The number 674 fits into 980 1 times, leaving a remainder of 306.
Use 1 as the next digit of our solution. 
Result so far: 128877.56231
The remainder is 306 after subtracting 674 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 14:
The number 674 fits into 3060 4 times, leaving a remainder of 364.
The next digit of our result is 4. 
Result so far: 128877.562314
Subtract 2696 from 3060 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 15:
When dividing 3640 by 674, we get 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 128877.5623145
If we subtract 3370 from 3640, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 16:
If we divide 2700 by 674, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 128877.56231454
If we subtract 2696 from 2700, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 128877.56231454 and a remainder of 4e-09.
