88989875 divided by 420 
We want to figure out the number of times 88989875 can be divided by 420.

Step 1:
If we divide 8 by 420, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 420

Moving on to step 2:
When dividing 88 by 420, we get 0 with a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 420

Going ahead to step 3:
The number 420 fits into 889 2 times, leaving a remainder of 49.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 840 from 889, we get 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 420

Advancing to step 4:
The number 420 fits into 498 1 times, leaving a remainder of 78.
The next digit of our result is 1. 
Result so far: 21.0
If we take 420 away from 498, we end up with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 420

On to step 5:
420 goes into 789 1 times with a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtracting 420 from 789 leaves us with 369.
Append the next digit (8) from the dividend to 369 and continue with: 3698 / 420

On to step 6:
If we divide 3698 by 420, we get 8 and a remainder of 338.
The next digit of our result is 8. 
Result so far: 2118.0
If we take 3360 away from 3698, we end up with 338.
Grab the next digit (7) from the dividend, add it to 338, then carry on: 3387 / 420

Advancing to step 7:
When dividing 3387 by 420, we get 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 21188.0
Subtracting 3360 from 3387 leaves us with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 420

Going ahead to step 8:
420 can be fit into 275 0 times, resulting in a remainder of 275.
Write down 0 as next digit of the result. 
Result so far: 211880.0
The remainder is 275 after subtracting 0 from 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 9:
2750 divided by 420 is 6 with a remainder of 230.
Write down 6 as next digit of the result. 
Result so far: 211880.6
If we take 2520 away from 2750, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
420 can be fit into 2300 5 times, resulting in a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 211880.65
If we subtract 2100 from 2300, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 211880.654
Deduct 1680 from 2000 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
If we divide 3200 by 420, we get 7 and a remainder of 260.
The next digit of our result is 7. 
Result so far: 211880.6547
If we take 2940 away from 3200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
2600 divided by 420 is 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 211880.65476
Subtract 2520 from 2600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
420 goes into 800 1 times with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 211880.654761
If we subtract 420 from 800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 15:
3800 divided by 420 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 211880.6547619
If we subtract 3780 from 3800, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
If we divide 200 by 420, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 211880.6547619
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 211880.6547619, with a leftover of 2e-07.
