We're dividing 61583210 by 731 
The aim is to understand the frequency of 731 in 61583210.

Going ahead to step 1:
If we divide 6 by 731, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our 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 / 731

On to step 2:
When dividing 61 by 731, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 731

Advancing to step 3:
615 divided by 731 is 0 with a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 615 to get 615.
Take the next digit (8) from the dividend and append it to 615, then repeat: 6158 / 731

Let's proceed to step 4:
731 goes into 6158 8 times with a remainder of 310.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 5848 from 6158 leaves us with 310.
Fetch the next digit (3) from the dividend, attach it to 310 and continue: 3103 / 731

Step 5:
3103 divided by 731 is 4 with a remainder of 179.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we take 2924 away from 3103, we end up with 179.
Grab the next digit (2) from the dividend, add it to 179, then carry on: 1792 / 731

On to step 6:
731 can be fit into 1792 2 times, resulting in a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 842.0
If we take 1462 away from 1792, we end up with 330.
Include the next digit (1) from the dividend after 330, then repeat: 3301 / 731

On to step 7:
731 can be fit into 3301 4 times, resulting in a remainder of 377.
Put 4 as the next digit of the answer. 
Result so far: 8424.0
If we take 2924 away from 3301, we end up with 377.
Grab the next digit (0) from the dividend, add it to 377, then carry on: 3770 / 731

Moving on to step 8:
731 can be fit into 3770 5 times, resulting in a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 84245.0
Subtracting 3655 from 3770 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 9:
731 goes into 1150 1 times with a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 84245.1
The remainder is 419 after subtracting 731 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 10:
When dividing 4190 by 731, we get 5 with a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 84245.15
The remainder is 535 after subtracting 3655 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 11:
731 can be fit into 5350 7 times, resulting in a remainder of 233.
The next digit of our result is 7. 
Result so far: 84245.157
If we take 5117 away from 5350, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 12:
The number 731 fits into 2330 3 times, leaving a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 84245.1573
If we subtract 2193 from 2330, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 13:
When dividing 1370 by 731, we get 1 with a remainder of 639.
Record the quotient 1 as the next digit in the result. 
Result so far: 84245.15731
Subtract 731 from 1370 to get 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 14:
6390 divided by 731 is 8 with a remainder of 542.
Put 8 as the next digit of the answer. 
Result so far: 84245.157318
Subtract 5848 from 6390 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 15:
If we divide 5420 by 731, we get 7 and a remainder of 303.
Write down 7 as next digit of the result. 
Result so far: 84245.1573187
Deduct 5117 from 5420 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 16:
731 can be fit into 3030 4 times, resulting in a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 84245.15731874
Deduct 2924 from 3030 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final outcome is 84245.15731874, with a leftover of 1.06e-07.
