37860101 divided by 730 
The aim is to understand the frequency of 730 in 37860101.

Let's proceed to step 1:
When dividing 3 by 730, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 730

Going ahead to step 2:
730 can be fit into 37 0 times, resulting in a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 730

On to step 3:
730 can be fit into 378 0 times, resulting in a remainder of 378.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 378 and we're left with 378.
Include the next digit (6) from the dividend after 378, then repeat: 3786 / 730

Let's proceed to step 4:
730 goes into 3786 5 times with a remainder of 136.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 136 after subtracting 3650 from 3786.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 730

On to step 5:
When dividing 1360 by 730, we get 1 with a remainder of 630.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 730 from 1360 and we're left with 630.
Include the next digit (1) from the dividend after 630, then repeat: 6301 / 730

On to step 6:
The number 730 fits into 6301 8 times, leaving a remainder of 461.
Use 8 as the next digit of our solution. 
Result so far: 518.0
If we subtract 5840 from 6301, we get 461.
Fetch the next digit (0) from the dividend, attach it to 461 and continue: 4610 / 730

Moving on to step 7:
4610 divided by 730 is 6 with a remainder of 230.
Write down 6 as next digit of the result. 
Result so far: 5186.0
Subtract 4380 from 4610 to get 230.
Append the next digit (1) from the dividend to 230 and continue with: 2301 / 730

Going ahead to step 8:
When dividing 2301 by 730, we get 3 with a remainder of 111.
Put 3 as the next digit of the answer. 
Result so far: 51863.0
Deduct 2190 from 2301 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
1110 divided by 730 is 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 51863.1
The remainder is 380 after subtracting 730 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
If we divide 3800 by 730, we get 5 and a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 51863.15
Deduct 3650 from 3800 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
If we divide 1500 by 730, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 51863.152
Subtract 1460 from 1500 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 730 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 51863.152
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
When dividing 4000 by 730, we get 5 with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 51863.15205
The remainder is 350 after subtracting 3650 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
730 goes into 3500 4 times with a remainder of 580.
Write down 4 as next digit of the result. 
Result so far: 51863.152054
If we subtract 2920 from 3500, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 15:
730 goes into 5800 7 times with a remainder of 690.
Put 7 as the next digit of the answer. 
Result so far: 51863.1520547
If we subtract 5110 from 5800, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 16:
730 can be fit into 6900 9 times, resulting in a remainder of 330.
Record the quotient 9 as the next digit in the result. 
Result so far: 51863.15205479
If we take 6570 away from 6900, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

After the division, we end up with 51863.15205479 and a remainder of 3.3e-07.
