We look at the division of 71902550 by 846 
The aim is to understand the frequency of 846 in 71902550.

Going ahead to step 1:
846 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 846

Moving on to step 2:
When dividing 71 by 846, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 846

On to step 3:
The number 846 fits into 719 0 times, leaving a remainder of 719.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 719 and we're left with 719.
Include the next digit (0) from the dividend after 719, then repeat: 7190 / 846

Advancing to step 4:
846 goes into 7190 8 times with a remainder of 422.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 6768 away from 7190, we end up with 422.
Grab the next digit (2) from the dividend, add it to 422, then carry on: 4222 / 846

On to step 5:
When dividing 4222 by 846, we get 4 with a remainder of 838.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 3384 from 4222 and we're left with 838.
Grab the next digit (5) from the dividend, add it to 838, then carry on: 8385 / 846

Step 6:
846 goes into 8385 9 times with a remainder of 771.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
If we subtract 7614 from 8385, we get 771.
Bring next digit (5) of the dividend behind the 771 and repeat the process: 7715 / 846

Advancing to step 7:
When dividing 7715 by 846, we get 9 with a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 8499.0
The remainder is 101 after subtracting 7614 from 7715.
Grab the next digit (0) from the dividend, add it to 101, then carry on: 1010 / 846

Going ahead to step 8:
846 goes into 1010 1 times with a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 84991.0
Subtract 846 from 1010 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 9:
The number 846 fits into 1640 1 times, leaving a remainder of 794.
The next digit of our result is 1. 
Result so far: 84991.1
If we take 846 away from 1640, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Step 10:
846 goes into 7940 9 times with a remainder of 326.
The number 9 becomes the next digit in our result. 
Result so far: 84991.19
If we take 7614 away from 7940, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 11:
If we divide 3260 by 846, we get 3 and a remainder of 722.
Put 3 as the next digit of the answer. 
Result so far: 84991.193
If we take 2538 away from 3260, we end up with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 12:
846 can be fit into 7220 8 times, resulting in a remainder of 452.
The number 8 becomes the next digit in our result. 
Result so far: 84991.1938
If we take 6768 away from 7220, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 13:
When dividing 4520 by 846, we get 5 with a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 84991.19385
If we subtract 4230 from 4520, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
When dividing 2900 by 846, we get 3 with a remainder of 362.
The number 3 becomes the next digit in our result. 
Result so far: 84991.193853
Subtracting 2538 from 2900 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 15:
3620 divided by 846 is 4 with a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 84991.1938534
If we subtract 3384 from 3620, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 16:
2360 divided by 846 is 2 with a remainder of 668.
Use 2 as the next digit of our solution. 
Result so far: 84991.19385342
Subtracting 1692 from 2360 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

The final outcome is 84991.19385342, with a leftover of 6.68e-07.
