We look at the division of 83158195 by 661 
We want to divide 83158195 by 661.

On to step 1:
When dividing 8 by 661, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 661

Let's proceed to step 2:
83 divided by 661 is 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 661

On to step 3:
If we divide 831 by 661, we get 1 and a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 661 from 831, we get 170.
Include the next digit (5) from the dividend after 170, then repeat: 1705 / 661

Going ahead to step 4:
1705 divided by 661 is 2 with a remainder of 383.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 383 after subtracting 1322 from 1705.
Append the next digit (8) from the dividend to 383 and continue with: 3838 / 661

Moving on to step 5:
If we divide 3838 by 661, we get 5 and a remainder of 533.
Write down 5 as next digit of the result. 
Result so far: 125.0
Deduct 3305 from 3838 and we're left with 533.
Append the next digit (1) from the dividend to 533 and continue with: 5331 / 661

Going ahead to step 6:
661 can be fit into 5331 8 times, resulting in a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 1258.0
If we subtract 5288 from 5331, we get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 661

Step 7:
When dividing 439 by 661, we get 0 with a remainder of 439.
Use 0 as the next digit of our solution. 
Result so far: 12580.0
The remainder is 439 after subtracting 0 from 439.
Take the next digit (5) from the dividend and append it to 439, then repeat: 4395 / 661

Let's proceed to step 8:
When dividing 4395 by 661, we get 6 with a remainder of 429.
The number 6 becomes the next digit in our result. 
Result so far: 125806.0
If we take 3966 away from 4395, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 9:
4290 divided by 661 is 6 with a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 125806.6
If we take 3966 away from 4290, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 10:
The number 661 fits into 3240 4 times, leaving a remainder of 596.
Use 4 as the next digit of our solution. 
Result so far: 125806.64
If we subtract 2644 from 3240, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 11:
When dividing 5960 by 661, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 125806.649
If we take 5949 away from 5960, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
When dividing 110 by 661, we get 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 125806.649
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 13:
1100 divided by 661 is 1 with a remainder of 439.
Record the quotient 1 as the next digit in the result. 
Result so far: 125806.64901
If we subtract 661 from 1100, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 14:
661 goes into 4390 6 times with a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 125806.649016
Deduct 3966 from 4390 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 15:
When dividing 4240 by 661, we get 6 with a remainder of 274.
Use 6 as the next digit of our solution. 
Result so far: 125806.6490166
If we subtract 3966 from 4240, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

After the division, we end up with 125806.6490166 and a remainder of 2.74e-06.
