66618541 ÷ 712 
We want to figure out the number of times 66618541 can be divided by 712.

Advancing to step 1:
712 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 712

Moving on to step 2:
66 divided by 712 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 712

Advancing to step 3:
If we divide 666 by 712, we get 0 and a remainder of 666.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 666, we end up with 666.
Fetch the next digit (1) from the dividend, attach it to 666 and continue: 6661 / 712

Going ahead to step 4:
If we divide 6661 by 712, we get 9 and a remainder of 253.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 6408 away from 6661, we end up with 253.
Fetch the next digit (8) from the dividend, attach it to 253 and continue: 2538 / 712

Let's proceed to step 5:
The number 712 fits into 2538 3 times, leaving a remainder of 402.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
The remainder is 402 after subtracting 2136 from 2538.
Include the next digit (5) from the dividend after 402, then repeat: 4025 / 712

On to step 6:
712 can be fit into 4025 5 times, resulting in a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 935.0
Deduct 3560 from 4025 and we're left with 465.
Include the next digit (4) from the dividend after 465, then repeat: 4654 / 712

Let's proceed to step 7:
712 goes into 4654 6 times with a remainder of 382.
The next digit of our result is 6. 
Result so far: 9356.0
If we take 4272 away from 4654, we end up with 382.
Take the next digit (1) from the dividend and append it to 382, then repeat: 3821 / 712

Going ahead to step 8:
If we divide 3821 by 712, we get 5 and a remainder of 261.
The number 5 becomes the next digit in our result. 
Result so far: 93565.0
Subtract 3560 from 3821 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 9:
The number 712 fits into 2610 3 times, leaving a remainder of 474.
Put 3 as the next digit of the answer. 
Result so far: 93565.3
The remainder is 474 after subtracting 2136 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 10:
712 can be fit into 4740 6 times, resulting in a remainder of 468.
Write down 6 as next digit of the result. 
Result so far: 93565.36
Subtract 4272 from 4740 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 11:
If we divide 4680 by 712, we get 6 and a remainder of 408.
The number 6 becomes the next digit in our result. 
Result so far: 93565.366
Subtract 4272 from 4680 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 93565.366, with a leftover of 0.0408.
