70178663 ÷ 406 
We're looking to find how many times 406 goes into 70178663.

Moving on to step 1:
7 divided by 406 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 406

Advancing to step 2:
When dividing 70 by 406, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 406

On to step 3:
When dividing 701 by 406, we get 1 with a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 406 from 701 and we're left with 295.
Fetch the next digit (7) from the dividend, attach it to 295 and continue: 2957 / 406

Moving on to step 4:
When dividing 2957 by 406, we get 7 with a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 2842 away from 2957, we end up with 115.
Bring next digit (8) of the dividend behind the 115 and repeat the process: 1158 / 406

Going ahead to step 5:
1158 divided by 406 is 2 with a remainder of 346.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 812 from 1158 leaves us with 346.
Fetch the next digit (6) from the dividend, attach it to 346 and continue: 3466 / 406

Advancing to step 6:
406 can be fit into 3466 8 times, resulting in a remainder of 218.
The number 8 becomes the next digit in our result. 
Result so far: 1728.0
Subtracting 3248 from 3466 leaves us with 218.
Grab the next digit (6) from the dividend, add it to 218, then carry on: 2186 / 406

On to step 7:
2186 divided by 406 is 5 with a remainder of 156.
The next digit of our result is 5. 
Result so far: 17285.0
Subtracting 2030 from 2186 leaves us with 156.
Include the next digit (3) from the dividend after 156, then repeat: 1563 / 406

Advancing to step 8:
406 can be fit into 1563 3 times, resulting in a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 172853.0
Subtract 1218 from 1563 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 9:
If we divide 3450 by 406, we get 8 and a remainder of 202.
The next digit of our result is 8. 
Result so far: 172853.8
If we subtract 3248 from 3450, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
When dividing 2020 by 406, we get 4 with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 172853.84
Subtract 1624 from 2020 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 11:
406 goes into 3960 9 times with a remainder of 306.
The number 9 becomes the next digit in our result. 
Result so far: 172853.849
Subtracting 3654 from 3960 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 12:
When dividing 3060 by 406, we get 7 with a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 172853.8497
Subtracting 2842 from 3060 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 13:
If we divide 2180 by 406, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 172853.84975
If we subtract 2030 from 2180, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
The number 406 fits into 1500 3 times, leaving a remainder of 282.
Use 3 as the next digit of our solution. 
Result so far: 172853.849753
If we take 1218 away from 1500, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 15:
The number 406 fits into 2820 6 times, leaving a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 172853.8497536
If we subtract 2436 from 2820, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 16:
3840 divided by 406 is 9 with a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 172853.84975369
The remainder is 186 after subtracting 3654 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final result is 172853.84975369 with a remainder of 1.86e-07.
