61579672 divided by 850 
The aim is to understand the frequency of 850 in 61579672.

Moving on to step 1:
850 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 850

Step 2:
The number 850 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 850

On to step 3:
When dividing 615 by 850, we get 0 with a remainder of 615.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 615 after subtracting 0 from 615.
Take the next digit (7) from the dividend and append it to 615, then repeat: 6157 / 850

Let's proceed to step 4:
The number 850 fits into 6157 7 times, leaving a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 5950 from 6157 to get 207.
Grab the next digit (9) from the dividend, add it to 207, then carry on: 2079 / 850

Going ahead to step 5:
If we divide 2079 by 850, we get 2 and a remainder of 379.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 1700 from 2079 to get 379.
Include the next digit (6) from the dividend after 379, then repeat: 3796 / 850

Advancing to step 6:
850 goes into 3796 4 times with a remainder of 396.
The next digit of our result is 4. 
Result so far: 724.0
If we take 3400 away from 3796, we end up with 396.
Append the next digit (7) from the dividend to 396 and continue with: 3967 / 850

Moving on to step 7:
850 goes into 3967 4 times with a remainder of 567.
The number 4 becomes the next digit in our result. 
Result so far: 7244.0
If we take 3400 away from 3967, we end up with 567.
Take the next digit (2) from the dividend and append it to 567, then repeat: 5672 / 850

Step 8:
850 goes into 5672 6 times with a remainder of 572.
Record the quotient 6 as the next digit in the result. 
Result so far: 72446.0
If we take 5100 away from 5672, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 9:
5720 divided by 850 is 6 with a remainder of 620.
Record the quotient 6 as the next digit in the result. 
Result so far: 72446.6
Deduct 5100 from 5720 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
The number 850 fits into 6200 7 times, leaving a remainder of 250.
The number 7 becomes the next digit in our result. 
Result so far: 72446.67
Subtracting 5950 from 6200 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
2500 divided by 850 is 2 with a remainder of 800.
The number 2 becomes the next digit in our result. 
Result so far: 72446.672
The remainder is 800 after subtracting 1700 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 12:
8000 divided by 850 is 9 with a remainder of 350.
The number 9 becomes the next digit in our result. 
Result so far: 72446.6729
Subtract 7650 from 8000 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 13:
When dividing 3500 by 850, we get 4 with a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 72446.67294
Subtracting 3400 from 3500 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
The number 850 fits into 1000 1 times, leaving a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 72446.672941
If we take 850 away from 1000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 15:
850 goes into 1500 1 times with a remainder of 650.
The number 1 becomes the next digit in our result. 
Result so far: 72446.6729411
Deduct 850 from 1500 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final outcome is 72446.6729411, with a leftover of 6.5e-06.
