We look at the division of 86458150 by 790 
Our goal is to divide 86458150 by 790.

Step 1:
790 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 790

Let's proceed to step 2:
790 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 790

Let's proceed to step 3:
The number 790 fits into 864 1 times, leaving a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 790 from 864 to get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 790

Advancing to step 4:
If we divide 745 by 790, we get 0 and a remainder of 745.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 745 after subtracting 0 from 745.
Fetch the next digit (8) from the dividend, attach it to 745 and continue: 7458 / 790

On to step 5:
When dividing 7458 by 790, we get 9 with a remainder of 348.
The next digit of our result is 9. 
Result so far: 109.0
Subtract 7110 from 7458 to get 348.
Fetch the next digit (1) from the dividend, attach it to 348 and continue: 3481 / 790

Going ahead to step 6:
The number 790 fits into 3481 4 times, leaving a remainder of 321.
Record the quotient 4 as the next digit in the result. 
Result so far: 1094.0
Deduct 3160 from 3481 and we're left with 321.
Grab the next digit (5) from the dividend, add it to 321, then carry on: 3215 / 790

Moving on to step 7:
If we divide 3215 by 790, we get 4 and a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 10944.0
Deduct 3160 from 3215 and we're left with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 790

Let's proceed to step 8:
If we divide 550 by 790, we get 0 and a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 109440.0
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 9:
When dividing 5500 by 790, we get 6 with a remainder of 760.
The number 6 becomes the next digit in our result. 
Result so far: 109440.6
Subtract 4740 from 5500 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 10:
When dividing 7600 by 790, we get 9 with a remainder of 490.
The next digit of our result is 9. 
Result so far: 109440.69
If we subtract 7110 from 7600, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
790 goes into 4900 6 times with a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 109440.696
If we take 4740 away from 4900, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
1600 divided by 790 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 109440.6962
Subtract 1580 from 1600 to 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.

Moving on to step 13:
790 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 109440.6962
If we subtract 0 from 200, 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.

On to step 14:
790 can be fit into 2000 2 times, resulting in a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 109440.696202
Deduct 1580 from 2000 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 15:
790 can be fit into 4200 5 times, resulting in a remainder of 250.
The next digit of our result is 5. 
Result so far: 109440.6962025
Subtract 3950 from 4200 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 16:
If we divide 2500 by 790, we get 3 and a remainder of 130.
The number 3 becomes the next digit in our result. 
Result so far: 109440.69620253
Subtracting 2370 from 2500 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 109440.69620253, with a leftover of 1.3e-07.
