37680391 ÷ 359 
The aim is to understand the frequency of 359 in 37680391.

Step 1:
If we divide 3 by 359, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 359

Moving on to step 2:
359 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 359

Let's proceed to step 3:
If we divide 376 by 359, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 359 from 376, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 359

Moving on to step 4:
If we divide 178 by 359, we get 0 and a remainder of 178.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 178, we get 178.
Append the next digit (0) from the dividend to 178 and continue with: 1780 / 359

Going ahead to step 5:
When dividing 1780 by 359, we get 4 with a remainder of 344.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtracting 1436 from 1780 leaves us with 344.
Include the next digit (3) from the dividend after 344, then repeat: 3443 / 359

Step 6:
3443 divided by 359 is 9 with a remainder of 212.
The next digit of our result is 9. 
Result so far: 1049.0
Subtracting 3231 from 3443 leaves us with 212.
Include the next digit (9) from the dividend after 212, then repeat: 2129 / 359

Let's proceed to step 7:
If we divide 2129 by 359, we get 5 and a remainder of 334.
The next digit of our result is 5. 
Result so far: 10495.0
Subtracting 1795 from 2129 leaves us with 334.
Grab the next digit (1) from the dividend, add it to 334, then carry on: 3341 / 359

Advancing to step 8:
3341 divided by 359 is 9 with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 104959.0
If we subtract 3231 from 3341, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 9:
359 can be fit into 1100 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 104959.3
If we subtract 1077 from 1100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
359 goes into 230 0 times with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 104959.3
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
If we divide 2300 by 359, we get 6 and a remainder of 146.
Record the quotient 6 as the next digit in the result. 
Result so far: 104959.306
Subtracting 2154 from 2300 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 12:
The number 359 fits into 1460 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 104959.3064
Deduct 1436 from 1460 and we're left 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.

On to step 13:
The number 359 fits into 240 0 times, leaving a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 104959.3064
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
If we divide 2400 by 359, we get 6 and a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 104959.306406
Subtract 2154 from 2400 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 15:
359 can be fit into 2460 6 times, resulting in a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 104959.3064066
If we take 2154 away from 2460, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The quotient of the division is 104959.3064066, and the remainder is 3.06e-06.
