We look at the division of 88876142 by 621 
We want to figure out the number of times 88876142 can be divided by 621.

On to step 1:
When dividing 8 by 621, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 621

Going ahead to step 2:
The number 621 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 621

Moving on to step 3:
621 can be fit into 888 1 times, resulting in a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 621 away from 888, we end up with 267.
Take the next digit (7) from the dividend and append it to 267, then repeat: 2677 / 621

Advancing to step 4:
2677 divided by 621 is 4 with a remainder of 193.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2484 away from 2677, we end up with 193.
Include the next digit (6) from the dividend after 193, then repeat: 1936 / 621

Going ahead to step 5:
When dividing 1936 by 621, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we subtract 1863 from 1936, we get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 621

Moving on to step 6:
621 goes into 731 1 times with a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 1431.0
If we take 621 away from 731, we end up with 110.
Fetch the next digit (4) from the dividend, attach it to 110 and continue: 1104 / 621

Let's proceed to step 7:
When dividing 1104 by 621, we get 1 with a remainder of 483.
Record the quotient 1 as the next digit in the result. 
Result so far: 14311.0
If we take 621 away from 1104, we end up with 483.
Include the next digit (2) from the dividend after 483, then repeat: 4832 / 621

Going ahead to step 8:
If we divide 4832 by 621, we get 7 and a remainder of 485.
The number 7 becomes the next digit in our result. 
Result so far: 143117.0
Deduct 4347 from 4832 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 9:
621 can be fit into 4850 7 times, resulting in a remainder of 503.
Put 7 as the next digit of the answer. 
Result so far: 143117.7
If we take 4347 away from 4850, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 10:
The number 621 fits into 5030 8 times, leaving a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 143117.78
Subtracting 4968 from 5030 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
If we divide 620 by 621, we get 0 and a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 143117.78
The remainder is 620 after subtracting 0 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 12:
621 can be fit into 6200 9 times, resulting in a remainder of 611.
Write down 9 as next digit of the result. 
Result so far: 143117.7809
If we take 5589 away from 6200, we end up with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Let's proceed to step 13:
621 goes into 6110 9 times with a remainder of 521.
The number 9 becomes the next digit in our result. 
Result so far: 143117.78099
Deduct 5589 from 6110 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

After the division, we end up with 143117.78099 and a remainder of 0.000521.
