We divide 70344953 by 839
The aim is to understand the frequency of 839 in 70344953.

On to step 1:
If we divide 7 by 839, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 839

Moving on to step 2:
If we divide 70 by 839, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 839

Advancing to step 3:
The number 839 fits into 703 0 times, leaving a remainder of 703.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 703, we end up with 703.
Include the next digit (4) from the dividend after 703, then repeat: 7034 / 839

Moving on to step 4:
When dividing 7034 by 839, we get 8 with a remainder of 322.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 6712 from 7034 leaves us with 322.
Bring next digit (4) of the dividend behind the 322 and repeat the process: 3224 / 839

Let's proceed to step 5:
839 goes into 3224 3 times with a remainder of 707.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 2517 from 3224 and we're left with 707.
Include the next digit (9) from the dividend after 707, then repeat: 7079 / 839

Advancing to step 6:
839 goes into 7079 8 times with a remainder of 367.
The next digit of our result is 8. 
Result so far: 838.0
If we subtract 6712 from 7079, we get 367.
Grab the next digit (5) from the dividend, add it to 367, then carry on: 3675 / 839

Step 7:
3675 divided by 839 is 4 with a remainder of 319.
Write down 4 as next digit of the result. 
Result so far: 8384.0
If we take 3356 away from 3675, we end up with 319.
Grab the next digit (3) from the dividend, add it to 319, then carry on: 3193 / 839

Step 8:
If we divide 3193 by 839, we get 3 and a remainder of 676.
Write down 3 as next digit of the result. 
Result so far: 83843.0
If we take 2517 away from 3193, we end up with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 9:
839 goes into 6760 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 83843.8
If we take 6712 away from 6760, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
If we divide 480 by 839, we get 0 and a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 83843.8
If we subtract 0 from 480, 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.

On to step 11:
839 can be fit into 4800 5 times, resulting in a remainder of 605.
The number 5 becomes the next digit in our result. 
Result so far: 83843.805
Subtract 4195 from 4800 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Advancing to step 12:
6050 divided by 839 is 7 with a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 83843.8057
Deduct 5873 from 6050 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 13:
839 goes into 1770 2 times with a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 83843.80572
Subtract 1678 from 1770 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
If we divide 920 by 839, we get 1 and a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 83843.805721
Deduct 839 from 920 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 15:
810 divided by 839 is 0 with a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 83843.805721
Subtracting 0 from 810 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 16:
When dividing 8100 by 839, we get 9 with a remainder of 549.
Write down 9 as next digit of the result. 
Result so far: 83843.80572109
Subtract 7551 from 8100 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

After the division, we end up with 83843.80572109 and a remainder of 5.49e-07.
