We're dividing 61377560 by 369 
The aim is to understand the frequency of 369 in 61377560.

On to step 1:
If we divide 6 by 369, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 369

Advancing to step 2:
61 divided by 369 is 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 369

On to step 3:
The number 369 fits into 613 1 times, leaving a remainder of 244.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 244 after subtracting 369 from 613.
Take the next digit (7) from the dividend and append it to 244, then repeat: 2447 / 369

Moving on to step 4:
369 goes into 2447 6 times with a remainder of 233.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 233 after subtracting 2214 from 2447.
Take the next digit (7) from the dividend and append it to 233, then repeat: 2337 / 369

Advancing to step 5:
The number 369 fits into 2337 6 times, leaving a remainder of 123.
The next digit of our result is 6. 
Result so far: 166.0
Subtract 2214 from 2337 to get 123.
Grab the next digit (5) from the dividend, add it to 123, then carry on: 1235 / 369

Moving on to step 6:
When dividing 1235 by 369, we get 3 with a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 1663.0
Subtract 1107 from 1235 to get 128.
Grab the next digit (6) from the dividend, add it to 128, then carry on: 1286 / 369

Going ahead to step 7:
369 can be fit into 1286 3 times, resulting in a remainder of 179.
Record the quotient 3 as the next digit in the result. 
Result so far: 16633.0
If we take 1107 away from 1286, we end up with 179.
Include the next digit (0) from the dividend after 179, then repeat: 1790 / 369

Advancing to step 8:
369 can be fit into 1790 4 times, resulting in a remainder of 314.
The next digit of our result is 4. 
Result so far: 166334.0
The remainder is 314 after subtracting 1476 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 9:
When dividing 3140 by 369, we get 8 with a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 166334.8
Deduct 2952 from 3140 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 10:
1880 divided by 369 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 166334.85
Subtract 1845 from 1880 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
350 divided by 369 is 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 166334.85
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
369 goes into 3500 9 times with a remainder of 179.
Put 9 as the next digit of the answer. 
Result so far: 166334.8509
Deduct 3321 from 3500 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 13:
The number 369 fits into 1790 4 times, leaving a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 166334.85094
The remainder is 314 after subtracting 1476 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 14:
369 goes into 3140 8 times with a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 166334.850948
Subtract 2952 from 3140 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 15:
When dividing 1880 by 369, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 166334.8509485
The remainder is 35 after subtracting 1845 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 16:
If we divide 350 by 369, we get 0 and a remainder of 350.
The next digit of our result is 0. 
Result so far: 166334.8509485
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The quotient of the division is 166334.8509485, and the remainder is 3.5e-07.
