We look at the division of 87942940 by 903 
We want to figure out the number of times 87942940 can be divided by 903.

Step 1:
903 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 903

Advancing to step 2:
If we divide 87 by 903, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 903

Let's proceed to step 3:
If we divide 879 by 903, we get 0 and a remainder of 879.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 879 to get 879.
Include the next digit (4) from the dividend after 879, then repeat: 8794 / 903

Advancing to step 4:
When dividing 8794 by 903, we get 9 with a remainder of 667.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 8127 from 8794, we get 667.
Append the next digit (2) from the dividend to 667 and continue with: 6672 / 903

Let's proceed to step 5:
903 can be fit into 6672 7 times, resulting in a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 6321 from 6672 and we're left with 351.
Include the next digit (9) from the dividend after 351, then repeat: 3519 / 903

Step 6:
If we divide 3519 by 903, we get 3 and a remainder of 810.
Use 3 as the next digit of our solution. 
Result so far: 973.0
If we take 2709 away from 3519, we end up with 810.
Include the next digit (4) from the dividend after 810, then repeat: 8104 / 903

Going ahead to step 7:
903 can be fit into 8104 8 times, resulting in a remainder of 880.
Write down 8 as next digit of the result. 
Result so far: 9738.0
Subtract 7224 from 8104 to get 880.
Take the next digit (0) from the dividend and append it to 880, then repeat: 8800 / 903

On to step 8:
903 can be fit into 8800 9 times, resulting in a remainder of 673.
The number 9 becomes the next digit in our result. 
Result so far: 97389.0
The remainder is 673 after subtracting 8127 from 8800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Let's proceed to step 9:
6730 divided by 903 is 7 with a remainder of 409.
Record the quotient 7 as the next digit in the result. 
Result so far: 97389.7
If we take 6321 away from 6730, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 10:
The number 903 fits into 4090 4 times, leaving a remainder of 478.
Use 4 as the next digit of our solution. 
Result so far: 97389.74
Deduct 3612 from 4090 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 11:
If we divide 4780 by 903, we get 5 and a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 97389.745
Deduct 4515 from 4780 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 12:
2650 divided by 903 is 2 with a remainder of 844.
Use 2 as the next digit of our solution. 
Result so far: 97389.7452
Subtract 1806 from 2650 to get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

On to step 13:
903 can be fit into 8440 9 times, resulting in a remainder of 313.
Record the quotient 9 as the next digit in the result. 
Result so far: 97389.74529
Deduct 8127 from 8440 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 14:
The number 903 fits into 3130 3 times, leaving a remainder of 421.
The number 3 becomes the next digit in our result. 
Result so far: 97389.745293
Subtracting 2709 from 3130 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 15:
4210 divided by 903 is 4 with a remainder of 598.
Put 4 as the next digit of the answer. 
Result so far: 97389.7452934
If we take 3612 away from 4210, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 16:
903 goes into 5980 6 times with a remainder of 562.
The number 6 becomes the next digit in our result. 
Result so far: 97389.74529346
Deduct 5418 from 5980 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

The final outcome is 97389.74529346, with a leftover of 5.62e-07.
