Let's divide 37598878 by 389
The aim is to understand the frequency of 389 in 37598878.

Step 1:
389 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 389

Advancing to step 2:
389 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 389

Moving on to step 3:
389 goes into 375 0 times with a remainder of 375.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 375, we end up with 375.
Append the next digit (9) from the dividend to 375 and continue with: 3759 / 389

Moving on to step 4:
3759 divided by 389 is 9 with a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 258 after subtracting 3501 from 3759.
Fetch the next digit (8) from the dividend, attach it to 258 and continue: 2588 / 389

Moving on to step 5:
2588 divided by 389 is 6 with a remainder of 254.
The next digit of our result is 6. 
Result so far: 96.0
The remainder is 254 after subtracting 2334 from 2588.
Take the next digit (8) from the dividend and append it to 254, then repeat: 2548 / 389

Advancing to step 6:
When dividing 2548 by 389, we get 6 with a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 966.0
The remainder is 214 after subtracting 2334 from 2548.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 389

Step 7:
When dividing 2147 by 389, we get 5 with a remainder of 202.
Use 5 as the next digit of our solution. 
Result so far: 9665.0
Subtracting 1945 from 2147 leaves us with 202.
Grab the next digit (8) from the dividend, add it to 202, then carry on: 2028 / 389

Step 8:
389 goes into 2028 5 times with a remainder of 83.
Record the quotient 5 as the next digit in the result. 
Result so far: 96655.0
If we subtract 1945 from 2028, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
If we divide 830 by 389, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 96655.2
Subtract 778 from 830 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
389 goes into 520 1 times with a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 96655.21
The remainder is 131 after subtracting 389 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 11:
389 goes into 1310 3 times with a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 96655.213
Subtract 1167 from 1310 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 12:
The number 389 fits into 1430 3 times, leaving a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 96655.2133
If we take 1167 away from 1430, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 96655.2133, with a leftover of 0.00263.
