We divide 99437680 by 290
The aim is to understand the frequency of 290 in 99437680.

Step 1:
If we divide 9 by 290, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 290

Advancing to step 2:
When dividing 99 by 290, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (4) from the dividend to 99 and continue with: 994 / 290

Advancing to step 3:
994 divided by 290 is 3 with a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 870 from 994 to get 124.
Append the next digit (3) from the dividend to 124 and continue with: 1243 / 290

Advancing to step 4:
When dividing 1243 by 290, we get 4 with a remainder of 83.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 1160 from 1243 and we're left with 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 290

Step 5:
837 divided by 290 is 2 with a remainder of 257.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
If we take 580 away from 837, we end up with 257.
Grab the next digit (6) from the dividend, add it to 257, then carry on: 2576 / 290

Moving on to step 6:
290 goes into 2576 8 times with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 3428.0
Deduct 2320 from 2576 and we're left with 256.
Fetch the next digit (8) from the dividend, attach it to 256 and continue: 2568 / 290

Advancing to step 7:
2568 divided by 290 is 8 with a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 34288.0
Deduct 2320 from 2568 and we're left with 248.
Take the next digit (0) from the dividend and append it to 248, then repeat: 2480 / 290

Moving on to step 8:
290 can be fit into 2480 8 times, resulting in a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 342888.0
Deduct 2320 from 2480 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
When dividing 1600 by 290, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 342888.5
The remainder is 150 after subtracting 1450 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
The number 290 fits into 1500 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 342888.55
Subtract 1450 from 1500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 342888.55 with a balance of 0.05.
