11139214 ÷ 840 
The aim is to understand the frequency of 840 in 11139214.

Advancing to step 1:
840 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 840

Going ahead to step 2:
If we divide 11 by 840, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 840

Step 3:
The number 840 fits into 111 0 times, leaving a remainder of 111.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 111 and we're left with 111.
Bring next digit (3) of the dividend behind the 111 and repeat the process: 1113 / 840

Going ahead to step 4:
If we divide 1113 by 840, we get 1 and a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 840 from 1113 leaves us with 273.
Grab the next digit (9) from the dividend, add it to 273, then carry on: 2739 / 840

Step 5:
2739 divided by 840 is 3 with a remainder of 219.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2520 from 2739 leaves us with 219.
Include the next digit (2) from the dividend after 219, then repeat: 2192 / 840

On to step 6:
840 can be fit into 2192 2 times, resulting in a remainder of 512.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtract 1680 from 2192 to get 512.
Append the next digit (1) from the dividend to 512 and continue with: 5121 / 840

Let's proceed to step 7:
The number 840 fits into 5121 6 times, leaving a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 1326.0
Deduct 5040 from 5121 and we're left with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 840

Step 8:
840 can be fit into 814 0 times, resulting in a remainder of 814.
Put 0 as the next digit of the answer. 
Result so far: 13260.0
Deduct 0 from 814 and we're left with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Let's proceed to step 9:
840 goes into 8140 9 times with a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 13260.9
Subtracting 7560 from 8140 leaves us with 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 10:
840 goes into 5800 6 times with a remainder of 760.
The number 6 becomes the next digit in our result. 
Result so far: 13260.96
Subtracting 5040 from 5800 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 11:
The number 840 fits into 7600 9 times, leaving a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 13260.969
If we take 7560 away from 7600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 840, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 13260.969
Subtracting 0 from 400 leaves us 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.

Advancing to step 13:
840 can be fit into 4000 4 times, resulting in a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 13260.96904
Subtracting 3360 from 4000 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 14:
6400 divided by 840 is 7 with a remainder of 520.
Write down 7 as next digit of the result. 
Result so far: 13260.969047
Deduct 5880 from 6400 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 15:
5200 divided by 840 is 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 13260.9690476
The remainder is 160 after subtracting 5040 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
If we divide 1600 by 840, we get 1 and a remainder of 760.
Write down 1 as next digit of the result. 
Result so far: 13260.96904761
If we subtract 840 from 1600, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

In conclusion, the division gives 13260.96904761 with a balance of 7.6e-07.
