6991098 ÷ 910 
The aim is to understand the frequency of 910 in 6991098.

Step 1:
6 divided by 910 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 910

Going ahead to step 2:
910 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 910

Let's proceed to step 3:
910 goes into 699 0 times with a remainder of 699.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 699 after subtracting 0 from 699.
Grab the next digit (1) from the dividend, add it to 699, then carry on: 6991 / 910

Let's proceed to step 4:
6991 divided by 910 is 7 with a remainder of 621.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 6370 away from 6991, we end up with 621.
Append the next digit (0) from the dividend to 621 and continue with: 6210 / 910

On to step 5:
If we divide 6210 by 910, we get 6 and a remainder of 750.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 5460 from 6210 to get 750.
Fetch the next digit (9) from the dividend, attach it to 750 and continue: 7509 / 910

Going ahead to step 6:
If we divide 7509 by 910, we get 8 and a remainder of 229.
Record the quotient 8 as the next digit in the result. 
Result so far: 768.0
If we subtract 7280 from 7509, we get 229.
Bring next digit (8) of the dividend behind the 229 and repeat the process: 2298 / 910

Advancing to step 7:
The number 910 fits into 2298 2 times, leaving a remainder of 478.
Use 2 as the next digit of our solution. 
Result so far: 7682.0
If we take 1820 away from 2298, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 8:
When dividing 4780 by 910, we get 5 with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 7682.5
If we take 4550 away from 4780, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 9:
The number 910 fits into 2300 2 times, leaving a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 7682.52
If we subtract 1820 from 2300, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 10:
4800 divided by 910 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 7682.525
Deduct 4550 from 4800 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 11:
910 can be fit into 2500 2 times, resulting in a remainder of 680.
Record the quotient 2 as the next digit in the result. 
Result so far: 7682.5252
The remainder is 680 after subtracting 1820 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 12:
When dividing 6800 by 910, we get 7 with a remainder of 430.
The number 7 becomes the next digit in our result. 
Result so far: 7682.52527
Subtracting 6370 from 6800 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 13:
910 goes into 4300 4 times with a remainder of 660.
Record the quotient 4 as the next digit in the result. 
Result so far: 7682.525274
If we subtract 3640 from 4300, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 14:
910 can be fit into 6600 7 times, resulting in a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 7682.5252747
Subtract 6370 from 6600 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.

Going ahead to step 15:
2300 divided by 910 is 2 with a remainder of 480.
The next digit of our result is 2. 
Result so far: 7682.52527472
Subtracting 1820 from 2300 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 7682.52527472, with a leftover of 4.8e-07.
