We look at the division of 73631734 by 861 
The aim is to understand the frequency of 861 in 73631734.

Moving on to step 1:
If we divide 7 by 861, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 861

Let's proceed to step 2:
861 goes into 73 0 times with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 861

Let's proceed to step 3:
861 can be fit into 736 0 times, resulting in a remainder of 736.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 736, we end up with 736.
Bring next digit (3) of the dividend behind the 736 and repeat the process: 7363 / 861

Advancing to step 4:
7363 divided by 861 is 8 with a remainder of 475.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 475 after subtracting 6888 from 7363.
Bring next digit (1) of the dividend behind the 475 and repeat the process: 4751 / 861

Let's proceed to step 5:
4751 divided by 861 is 5 with a remainder of 446.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtracting 4305 from 4751 leaves us with 446.
Grab the next digit (7) from the dividend, add it to 446, then carry on: 4467 / 861

Going ahead to step 6:
861 goes into 4467 5 times with a remainder of 162.
Write down 5 as next digit of the result. 
Result so far: 855.0
If we subtract 4305 from 4467, we get 162.
Take the next digit (3) from the dividend and append it to 162, then repeat: 1623 / 861

Step 7:
1623 divided by 861 is 1 with a remainder of 762.
Put 1 as the next digit of the answer. 
Result so far: 8551.0
Subtracting 861 from 1623 leaves us with 762.
Fetch the next digit (4) from the dividend, attach it to 762 and continue: 7624 / 861

Advancing to step 8:
The number 861 fits into 7624 8 times, leaving a remainder of 736.
The number 8 becomes the next digit in our result. 
Result so far: 85518.0
Subtract 6888 from 7624 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 9:
The number 861 fits into 7360 8 times, leaving a remainder of 472.
Put 8 as the next digit of the answer. 
Result so far: 85518.8
Subtract 6888 from 7360 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 10:
861 can be fit into 4720 5 times, resulting in a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 85518.85
If we take 4305 away from 4720, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 11:
If we divide 4150 by 861, we get 4 and a remainder of 706.
Record the quotient 4 as the next digit in the result. 
Result so far: 85518.854
Subtract 3444 from 4150 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Let's proceed to step 12:
When dividing 7060 by 861, we get 8 with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 85518.8548
Subtracting 6888 from 7060 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 13:
1720 divided by 861 is 1 with a remainder of 859.
The next digit of our result is 1. 
Result so far: 85518.85481
If we take 861 away from 1720, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Let's proceed to step 14:
When dividing 8590 by 861, we get 9 with a remainder of 841.
Use 9 as the next digit of our solution. 
Result so far: 85518.854819
If we take 7749 away from 8590, we end up with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Advancing to step 15:
861 can be fit into 8410 9 times, resulting in a remainder of 661.
Write down 9 as next digit of the result. 
Result so far: 85518.8548199
Subtracting 7749 from 8410 leaves us with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

The quotient of the division is 85518.8548199, and the remainder is 6.61e-06.
