We're dividing 86981702 by 369 
The aim is to understand the frequency of 369 in 86981702.

Going ahead to step 1:
The number 369 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 369

Moving on to step 2:
The number 369 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 369

Going ahead to step 3:
When dividing 869 by 369, we get 2 with a remainder of 131.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 738 from 869, we get 131.
Take the next digit (8) from the dividend and append it to 131, then repeat: 1318 / 369

On to step 4:
369 goes into 1318 3 times with a remainder of 211.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 1107 from 1318 to get 211.
Append the next digit (1) from the dividend to 211 and continue with: 2111 / 369

Going ahead to step 5:
2111 divided by 369 is 5 with a remainder of 266.
Use 5 as the next digit of our solution. 
Result so far: 235.0
Subtracting 1845 from 2111 leaves us with 266.
Include the next digit (7) from the dividend after 266, then repeat: 2667 / 369

On to step 6:
369 goes into 2667 7 times with a remainder of 84.
Write down 7 as next digit of the result. 
Result so far: 2357.0
If we take 2583 away from 2667, we end up with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 369

Let's proceed to step 7:
369 goes into 840 2 times with a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 23572.0
The remainder is 102 after subtracting 738 from 840.
Append the next digit (2) from the dividend to 102 and continue with: 1022 / 369

Advancing to step 8:
1022 divided by 369 is 2 with a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 235722.0
Deduct 738 from 1022 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 9:
When dividing 2840 by 369, we get 7 with a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 235722.7
If we subtract 2583 from 2840, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 10:
369 goes into 2570 6 times with a remainder of 356.
Use 6 as the next digit of our solution. 
Result so far: 235722.76
If we take 2214 away from 2570, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 11:
3560 divided by 369 is 9 with a remainder of 239.
Use 9 as the next digit of our solution. 
Result so far: 235722.769
The remainder is 239 after subtracting 3321 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 12:
2390 divided by 369 is 6 with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 235722.7696
The remainder is 176 after subtracting 2214 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
369 goes into 1760 4 times with a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 235722.76964
If we subtract 1476 from 1760, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 14:
2840 divided by 369 is 7 with a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 235722.769647
Subtracting 2583 from 2840 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 15:
2570 divided by 369 is 6 with a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 235722.7696476
Deduct 2214 from 2570 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 16:
If we divide 3560 by 369, we get 9 and a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 235722.76964769
Deduct 3321 from 3560 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

After the division, we end up with 235722.76964769 and a remainder of 2.39e-07.
