We look at the division of 87979521 by 373 
We want to figure out the number of times 87979521 can be divided by 373.

Step 1:
373 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 373

Let's proceed to step 2:
If we divide 87 by 373, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 373

Step 3:
When dividing 879 by 373, we get 2 with a remainder of 133.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 746 from 879 to get 133.
Append the next digit (7) from the dividend to 133 and continue with: 1337 / 373

Going ahead to step 4:
373 can be fit into 1337 3 times, resulting in a remainder of 218.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 1119 from 1337 leaves us with 218.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 373

On to step 5:
373 goes into 2189 5 times with a remainder of 324.
Write down 5 as next digit of the result. 
Result so far: 235.0
Subtract 1865 from 2189 to get 324.
Include the next digit (5) from the dividend after 324, then repeat: 3245 / 373

Let's proceed to step 6:
3245 divided by 373 is 8 with a remainder of 261.
The next digit of our result is 8. 
Result so far: 2358.0
The remainder is 261 after subtracting 2984 from 3245.
Take the next digit (2) from the dividend and append it to 261, then repeat: 2612 / 373

Step 7:
373 can be fit into 2612 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 23587.0
If we take 2611 away from 2612, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 373

On to step 8:
The number 373 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 235870.0
The remainder is 11 after subtracting 0 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 373 fits into 110 0 times, leaving a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 235870.0
Subtracting 0 from 110 leaves us 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:
373 goes into 1100 2 times with a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 235870.02
The remainder is 354 after subtracting 746 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 11:
If we divide 3540 by 373, we get 9 and a remainder of 183.
Put 9 as the next digit of the answer. 
Result so far: 235870.029
Subtract 3357 from 3540 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 12:
When dividing 1830 by 373, we get 4 with a remainder of 338.
Use 4 as the next digit of our solution. 
Result so far: 235870.0294
If we subtract 1492 from 1830, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 13:
The number 373 fits into 3380 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 235870.02949
Subtracting 3357 from 3380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
373 goes into 230 0 times with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 235870.02949
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 15:
The number 373 fits into 2300 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 235870.0294906
If we subtract 2238 from 2300, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 16:
The number 373 fits into 620 1 times, leaving a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 235870.02949061
If we subtract 373 from 620, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

The quotient of the division is 235870.02949061, and the remainder is 2.47e-07.
