We look at the division of 88621944 by 858 
We want to figure out the number of times 88621944 can be divided by 858.

Going ahead to step 1:
858 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 858

Let's proceed to step 2:
The number 858 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 858

Step 3:
886 divided by 858 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 858 from 886 leaves us with 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 858

Step 4:
When dividing 282 by 858, we get 0 with a remainder of 282.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 282 and we're left with 282.
Append the next digit (1) from the dividend to 282 and continue with: 2821 / 858

Advancing to step 5:
The number 858 fits into 2821 3 times, leaving a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtracting 2574 from 2821 leaves us with 247.
Append the next digit (9) from the dividend to 247 and continue with: 2479 / 858

On to step 6:
When dividing 2479 by 858, we get 2 with a remainder of 763.
Write down 2 as next digit of the result. 
Result so far: 1032.0
Subtracting 1716 from 2479 leaves us with 763.
Grab the next digit (4) from the dividend, add it to 763, then carry on: 7634 / 858

Moving on to step 7:
When dividing 7634 by 858, we get 8 with a remainder of 770.
Record the quotient 8 as the next digit in the result. 
Result so far: 10328.0
If we take 6864 away from 7634, we end up with 770.
Grab the next digit (4) from the dividend, add it to 770, then carry on: 7704 / 858

Advancing to step 8:
When dividing 7704 by 858, we get 8 with a remainder of 840.
Put 8 as the next digit of the answer. 
Result so far: 103288.0
The remainder is 840 after subtracting 6864 from 7704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 9:
8400 divided by 858 is 9 with a remainder of 678.
Use 9 as the next digit of our solution. 
Result so far: 103288.9
If we take 7722 away from 8400, we end up with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

On to step 10:
When dividing 6780 by 858, we get 7 with a remainder of 774.
The number 7 becomes the next digit in our result. 
Result so far: 103288.97
Subtract 6006 from 6780 to get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Let's proceed to step 11:
858 can be fit into 7740 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 103288.979
If we take 7722 away from 7740, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 858 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 103288.979
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
858 goes into 1800 2 times with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 103288.97902
Deduct 1716 from 1800 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
858 goes into 840 0 times with a remainder of 840.
Record the quotient 0 as the next digit in the result. 
Result so far: 103288.97902
If we subtract 0 from 840, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 15:
When dividing 8400 by 858, we get 9 with a remainder of 678.
Use 9 as the next digit of our solution. 
Result so far: 103288.9790209
Subtract 7722 from 8400 to get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 16:
If we divide 6780 by 858, we get 7 and a remainder of 774.
Write down 7 as next digit of the result. 
Result so far: 103288.97902097
If we take 6006 away from 6780, we end up with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

The final result is 103288.97902097 with a remainder of 7.74e-07.
