56561788 divided by 903 
The aim is to understand the frequency of 903 in 56561788.

Advancing to step 1:
When dividing 5 by 903, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 903

Let's proceed to step 2:
The number 903 fits into 56 0 times, leaving a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 903

On to step 3:
When dividing 565 by 903, we get 0 with a remainder of 565.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 565, we get 565.
Take the next digit (6) from the dividend and append it to 565, then repeat: 5656 / 903

On to step 4:
The number 903 fits into 5656 6 times, leaving a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5418 from 5656 and we're left with 238.
Bring next digit (1) of the dividend behind the 238 and repeat the process: 2381 / 903

Step 5:
If we divide 2381 by 903, we get 2 and a remainder of 575.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 1806 from 2381 and we're left with 575.
Append the next digit (7) from the dividend to 575 and continue with: 5757 / 903

Advancing to step 6:
903 can be fit into 5757 6 times, resulting in a remainder of 339.
Write down 6 as next digit of the result. 
Result so far: 626.0
Subtract 5418 from 5757 to get 339.
Include the next digit (8) from the dividend after 339, then repeat: 3398 / 903

On to step 7:
903 goes into 3398 3 times with a remainder of 689.
Use 3 as the next digit of our solution. 
Result so far: 6263.0
Subtract 2709 from 3398 to get 689.
Take the next digit (8) from the dividend and append it to 689, then repeat: 6898 / 903

Going ahead to step 8:
If we divide 6898 by 903, we get 7 and a remainder of 577.
Write down 7 as next digit of the result. 
Result so far: 62637.0
If we take 6321 away from 6898, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 9:
903 goes into 5770 6 times with a remainder of 352.
The next digit of our result is 6. 
Result so far: 62637.6
The remainder is 352 after subtracting 5418 from 5770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 10:
The number 903 fits into 3520 3 times, leaving a remainder of 811.
Write down 3 as next digit of the result. 
Result so far: 62637.63
Deduct 2709 from 3520 and we're left with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Moving on to step 11:
If we divide 8110 by 903, we get 8 and a remainder of 886.
Put 8 as the next digit of the answer. 
Result so far: 62637.638
Deduct 7224 from 8110 and we're left with 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8860, and continue the process.

Step 12:
903 can be fit into 8860 9 times, resulting in a remainder of 733.
Record the quotient 9 as the next digit in the result. 
Result so far: 62637.6389
Subtracting 8127 from 8860 leaves us with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Step 13:
When dividing 7330 by 903, we get 8 with a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 62637.63898
Deduct 7224 from 7330 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.

Going ahead to step 14:
1060 divided by 903 is 1 with a remainder of 157.
The next digit of our result is 1. 
Result so far: 62637.638981
Deduct 903 from 1060 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 15:
If we divide 1570 by 903, we get 1 and a remainder of 667.
Write down 1 as next digit of the result. 
Result so far: 62637.6389811
Subtract 903 from 1570 to get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

After the division, we end up with 62637.6389811 and a remainder of 6.67e-06.
