We look at the division of 39913136 by 850 
The aim is to understand the frequency of 850 in 39913136.

Let's proceed to step 1:
850 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 850

Advancing to step 2:
When dividing 39 by 850, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 850

Advancing to step 3:
When dividing 399 by 850, we get 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Bring next digit (1) of the dividend behind the 399 and repeat the process: 3991 / 850

Advancing to step 4:
The number 850 fits into 3991 4 times, leaving a remainder of 591.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3400 from 3991 to get 591.
Take the next digit (3) from the dividend and append it to 591, then repeat: 5913 / 850

On to step 5:
The number 850 fits into 5913 6 times, leaving a remainder of 813.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
The remainder is 813 after subtracting 5100 from 5913.
Bring next digit (1) of the dividend behind the 813 and repeat the process: 8131 / 850

Let's proceed to step 6:
The number 850 fits into 8131 9 times, leaving a remainder of 481.
Use 9 as the next digit of our solution. 
Result so far: 469.0
The remainder is 481 after subtracting 7650 from 8131.
Grab the next digit (3) from the dividend, add it to 481, then carry on: 4813 / 850

Moving on to step 7:
When dividing 4813 by 850, we get 5 with a remainder of 563.
Record the quotient 5 as the next digit in the result. 
Result so far: 4695.0
If we subtract 4250 from 4813, we get 563.
Fetch the next digit (6) from the dividend, attach it to 563 and continue: 5636 / 850

Advancing to step 8:
5636 divided by 850 is 6 with a remainder of 536.
Record the quotient 6 as the next digit in the result. 
Result so far: 46956.0
Subtract 5100 from 5636 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 9:
The number 850 fits into 5360 6 times, leaving a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 46956.6
Subtract 5100 from 5360 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
2600 divided by 850 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 46956.63
If we subtract 2550 from 2600, we 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.

Moving on to step 11:
500 divided by 850 is 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 46956.63
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 12:
850 goes into 5000 5 times with a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 46956.6305
Subtracting 4250 from 5000 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 13:
The number 850 fits into 7500 8 times, leaving a remainder of 700.
Write down 8 as next digit of the result. 
Result so far: 46956.63058
Subtract 6800 from 7500 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 14:
850 goes into 7000 8 times with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 46956.630588
Deduct 6800 from 7000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 46956.630588 with a remainder of 2e-05.
