139883 divided by 70 
The aim is to understand the frequency of 70 in 139883.

Advancing to step 1:
70 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
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 70

Moving on to step 2:
When dividing 13 by 70, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 70

Advancing to step 3:
If we divide 139 by 70, we get 1 and a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 70 from 139 leaves us with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 70

Step 4:
When dividing 698 by 70, we get 9 with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 630 from 698 and we're left with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 70

Advancing to step 5:
The number 70 fits into 688 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 199.0
If we take 630 away from 688, we end up with 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 70

On to step 6:
70 can be fit into 583 8 times, resulting in a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 1998.0
Subtract 560 from 583 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
70 goes into 230 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1998.3
If we subtract 210 from 230, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1998.32
If we take 140 away from 200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1998.328
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1998.3285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1998.32857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1998.328571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1998.3285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1998.32857142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 1998.32857142, with a leftover of 6e-08.
