70055645 ÷ 661 
Our goal is to divide 70055645 by 661.

Advancing to step 1:
661 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 661

Let's proceed to step 2:
The number 661 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 661

Let's proceed to step 3:
When dividing 700 by 661, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 661 from 700 leaves us with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 661

Advancing to step 4:
661 can be fit into 395 0 times, resulting in a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 395 and we're left with 395.
Include the next digit (5) from the dividend after 395, then repeat: 3955 / 661

On to step 5:
661 goes into 3955 5 times with a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 3305 from 3955 leaves us with 650.
Bring next digit (6) of the dividend behind the 650 and repeat the process: 6506 / 661

Let's proceed to step 6:
661 can be fit into 6506 9 times, resulting in a remainder of 557.
Record the quotient 9 as the next digit in the result. 
Result so far: 1059.0
Subtracting 5949 from 6506 leaves us with 557.
Grab the next digit (4) from the dividend, add it to 557, then carry on: 5574 / 661

Let's proceed to step 7:
661 can be fit into 5574 8 times, resulting in a remainder of 286.
Write down 8 as next digit of the result. 
Result so far: 10598.0
Subtract 5288 from 5574 to get 286.
Include the next digit (5) from the dividend after 286, then repeat: 2865 / 661

Advancing to step 8:
661 goes into 2865 4 times with a remainder of 221.
Record the quotient 4 as the next digit in the result. 
Result so far: 105984.0
If we subtract 2644 from 2865, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
If we divide 2210 by 661, we get 3 and a remainder of 227.
Use 3 as the next digit of our solution. 
Result so far: 105984.3
Subtract 1983 from 2210 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 10:
The number 661 fits into 2270 3 times, leaving a remainder of 287.
Write down 3 as next digit of the result. 
Result so far: 105984.33
If we take 1983 away from 2270, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Our division results in 105984.33 with a remaining 0.287.
