We divide 85089808 by 731
The aim is to understand the frequency of 731 in 85089808.

Step 1:
The number 731 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 731

On to step 2:
731 goes into 85 0 times with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 731

On to step 3:
731 can be fit into 850 1 times, resulting in a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 731 from 850, we get 119.
Grab the next digit (8) from the dividend, add it to 119, then carry on: 1198 / 731

On to step 4:
If we divide 1198 by 731, we get 1 and a remainder of 467.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 731 from 1198 to get 467.
Bring next digit (9) of the dividend behind the 467 and repeat the process: 4679 / 731

Step 5:
When dividing 4679 by 731, we get 6 with a remainder of 293.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 4386 from 4679, we get 293.
Take the next digit (8) from the dividend and append it to 293, then repeat: 2938 / 731

Moving on to step 6:
If we divide 2938 by 731, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1164.0
If we take 2924 away from 2938, we end up with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 731

Step 7:
731 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 11640.0
Subtract 0 from 140 to get 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 731

On to step 8:
731 can be fit into 1408 1 times, resulting in a remainder of 677.
Put 1 as the next digit of the answer. 
Result so far: 116401.0
Subtract 731 from 1408 to get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 9:
If we divide 6770 by 731, we get 9 and a remainder of 191.
Record the quotient 9 as the next digit in the result. 
Result so far: 116401.9
The remainder is 191 after subtracting 6579 from 6770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 10:
When dividing 1910 by 731, we get 2 with a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 116401.92
If we take 1462 away from 1910, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 11:
When dividing 4480 by 731, we get 6 with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 116401.926
If we subtract 4386 from 4480, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 12:
When dividing 940 by 731, we get 1 with a remainder of 209.
The next digit of our result is 1. 
Result so far: 116401.9261
Subtracting 731 from 940 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 13:
2090 divided by 731 is 2 with a remainder of 628.
The next digit of our result is 2. 
Result so far: 116401.92612
Subtracting 1462 from 2090 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 14:
731 can be fit into 6280 8 times, resulting in a remainder of 432.
Record the quotient 8 as the next digit in the result. 
Result so far: 116401.926128
Deduct 5848 from 6280 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 15:
When dividing 4320 by 731, we get 5 with a remainder of 665.
Record the quotient 5 as the next digit in the result. 
Result so far: 116401.9261285
Subtracting 3655 from 4320 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Moving on to step 16:
6650 divided by 731 is 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 116401.92612859
Deduct 6579 from 6650 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 116401.92612859, with a leftover of 7.1e-08.
