83291015 ÷ 406 
We want to figure out the number of times 83291015 can be divided by 406.

Step 1:
The number 406 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 406

Let's proceed to step 2:
406 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (2) from the dividend to 83 and continue with: 832 / 406

Going ahead to step 3:
406 goes into 832 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 812 away from 832, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 406

Step 4:
When dividing 209 by 406, we get 0 with a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (1) of the dividend behind the 209 and repeat the process: 2091 / 406

Step 5:
2091 divided by 406 is 5 with a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
If we take 2030 away from 2091, we end up with 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 406

Advancing to step 6:
406 goes into 610 1 times with a remainder of 204.
Use 1 as the next digit of our solution. 
Result so far: 2051.0
Subtracting 406 from 610 leaves us with 204.
Grab the next digit (1) from the dividend, add it to 204, then carry on: 2041 / 406

Step 7:
406 goes into 2041 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 20515.0
If we subtract 2030 from 2041, we get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 406

On to step 8:
406 can be fit into 115 0 times, resulting in a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 205150.0
If we take 0 away from 115, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
If we divide 1150 by 406, we get 2 and a remainder of 338.
The next digit of our result is 2. 
Result so far: 205150.2
If we subtract 812 from 1150, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
When dividing 3380 by 406, we get 8 with a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 205150.28
Subtract 3248 from 3380 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
If we divide 1320 by 406, we get 3 and a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 205150.283
The remainder is 102 after subtracting 1218 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
406 can be fit into 1020 2 times, resulting in a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 205150.2832
Deduct 812 from 1020 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
406 can be fit into 2080 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 205150.28325
Deduct 2030 from 2080 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
406 can be fit into 500 1 times, resulting in a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 205150.283251
If we take 406 away from 500, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 15:
940 divided by 406 is 2 with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 205150.2832512
Subtract 812 from 940 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 16:
When dividing 1280 by 406, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 205150.28325123
Subtracting 1218 from 1280 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 205150.28325123, with a leftover of 6.2e-08.
