We look at the division of 53497859 by 860 
The aim is to understand the frequency of 860 in 53497859.

Going ahead to step 1:
When dividing 5 by 860, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 860

Moving on to step 2:
When dividing 53 by 860, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 860

On to step 3:
860 can be fit into 534 0 times, resulting in a remainder of 534.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Fetch the next digit (9) from the dividend, attach it to 534 and continue: 5349 / 860

Going ahead to step 4:
860 goes into 5349 6 times with a remainder of 189.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5160 from 5349 leaves us with 189.
Fetch the next digit (7) from the dividend, attach it to 189 and continue: 1897 / 860

Advancing to step 5:
When dividing 1897 by 860, we get 2 with a remainder of 177.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we subtract 1720 from 1897, we get 177.
Append the next digit (8) from the dividend to 177 and continue with: 1778 / 860

Going ahead to step 6:
If we divide 1778 by 860, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 622.0
Deduct 1720 from 1778 and we're left with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 860

Going ahead to step 7:
585 divided by 860 is 0 with a remainder of 585.
Use 0 as the next digit of our solution. 
Result so far: 6220.0
If we take 0 away from 585, we end up with 585.
Take the next digit (9) from the dividend and append it to 585, then repeat: 5859 / 860

Moving on to step 8:
860 can be fit into 5859 6 times, resulting in a remainder of 699.
Record the quotient 6 as the next digit in the result. 
Result so far: 62206.0
Deduct 5160 from 5859 and we're left with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

On to step 9:
The number 860 fits into 6990 8 times, leaving a remainder of 110.
The next digit of our result is 8. 
Result so far: 62206.8
If we take 6880 away from 6990, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 860, we get 1 with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 62206.81
Subtract 860 from 1100 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
2400 divided by 860 is 2 with a remainder of 680.
Write down 2 as next digit of the result. 
Result so far: 62206.812
Subtracting 1720 from 2400 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 12:
The number 860 fits into 6800 7 times, leaving a remainder of 780.
Put 7 as the next digit of the answer. 
Result so far: 62206.8127
If we subtract 6020 from 6800, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 13:
860 can be fit into 7800 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 62206.81279
The remainder is 60 after subtracting 7740 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
When dividing 600 by 860, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 62206.81279
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 15:
6000 divided by 860 is 6 with a remainder of 840.
The number 6 becomes the next digit in our result. 
Result so far: 62206.8127906
Subtract 5160 from 6000 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 16:
The number 860 fits into 8400 9 times, leaving a remainder of 660.
The next digit of our result is 9. 
Result so far: 62206.81279069
If we take 7740 away from 8400, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The quotient of the division is 62206.81279069, and the remainder is 6.6e-07.
