We look at the division of 86102234 by 425 
We want to figure out the number of times 86102234 can be divided by 425.

Going ahead to step 1:
425 can be fit into 8 0 times, resulting in 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.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 425

Advancing to step 2:
When dividing 86 by 425, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 425

Step 3:
If we divide 861 by 425, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 850 from 861 to get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 425

On to step 4:
425 goes into 110 0 times with a remainder of 110.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 110, we end up with 110.
Fetch the next digit (2) from the dividend, attach it to 110 and continue: 1102 / 425

On to step 5:
The number 425 fits into 1102 2 times, leaving a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 202.0
The remainder is 252 after subtracting 850 from 1102.
Take the next digit (2) from the dividend and append it to 252, then repeat: 2522 / 425

Moving on to step 6:
The number 425 fits into 2522 5 times, leaving a remainder of 397.
The number 5 becomes the next digit in our result. 
Result so far: 2025.0
Subtract 2125 from 2522 to get 397.
Fetch the next digit (3) from the dividend, attach it to 397 and continue: 3973 / 425

Moving on to step 7:
425 goes into 3973 9 times with a remainder of 148.
Write down 9 as next digit of the result. 
Result so far: 20259.0
Deduct 3825 from 3973 and we're left with 148.
Fetch the next digit (4) from the dividend, attach it to 148 and continue: 1484 / 425

Advancing to step 8:
1484 divided by 425 is 3 with a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 202593.0
Subtract 1275 from 1484 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
425 can be fit into 2090 4 times, resulting in a remainder of 390.
The next digit of our result is 4. 
Result so far: 202593.4
Deduct 1700 from 2090 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
The number 425 fits into 3900 9 times, leaving a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 202593.49
Deduct 3825 from 3900 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
The number 425 fits into 750 1 times, leaving a remainder of 325.
Use 1 as the next digit of our solution. 
Result so far: 202593.491
Subtract 425 from 750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 12:
If we divide 3250 by 425, we get 7 and a remainder of 275.
Record the quotient 7 as the next digit in the result. 
Result so far: 202593.4917
Subtract 2975 from 3250 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 13:
425 can be fit into 2750 6 times, resulting in a remainder of 200.
The next digit of our result is 6. 
Result so far: 202593.49176
Subtracting 2550 from 2750 leaves us 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.

Moving on to step 14:
If we divide 2000 by 425, we get 4 and a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 202593.491764
The remainder is 300 after subtracting 1700 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 15:
425 goes into 3000 7 times with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 202593.4917647
If we take 2975 away from 3000, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 16:
425 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 202593.4917647
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

After the division, we end up with 202593.4917647 and a remainder of 2.5e-07.
