We're dividing 66603709 by 891 
Our goal is to divide 66603709 by 891.

Advancing to step 1:
891 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 891

On to step 2:
66 divided by 891 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 891

Let's proceed to step 3:
666 divided by 891 is 0 with a remainder of 666.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 666 to get 666.
Include the next digit (0) from the dividend after 666, then repeat: 6660 / 891

Moving on to step 4:
The number 891 fits into 6660 7 times, leaving a remainder of 423.
The next digit of our result is 7. 
Result so far: 7.0
If we take 6237 away from 6660, we end up with 423.
Take the next digit (3) from the dividend and append it to 423, then repeat: 4233 / 891

Step 5:
If we divide 4233 by 891, we get 4 and a remainder of 669.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we take 3564 away from 4233, we end up with 669.
Include the next digit (7) from the dividend after 669, then repeat: 6697 / 891

Moving on to step 6:
891 can be fit into 6697 7 times, resulting in a remainder of 460.
The number 7 becomes the next digit in our result. 
Result so far: 747.0
If we subtract 6237 from 6697, we get 460.
Append the next digit (0) from the dividend to 460 and continue with: 4600 / 891

Step 7:
891 goes into 4600 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 7475.0
If we subtract 4455 from 4600, we get 145.
Take the next digit (9) from the dividend and append it to 145, then repeat: 1459 / 891

Advancing to step 8:
When dividing 1459 by 891, we get 1 with a remainder of 568.
Record the quotient 1 as the next digit in the result. 
Result so far: 74751.0
If we take 891 away from 1459, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 9:
If we divide 5680 by 891, we get 6 and a remainder of 334.
The number 6 becomes the next digit in our result. 
Result so far: 74751.6
If we subtract 5346 from 5680, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 10:
3340 divided by 891 is 3 with a remainder of 667.
The number 3 becomes the next digit in our result. 
Result so far: 74751.63
If we take 2673 away from 3340, we end up with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Advancing to step 11:
When dividing 6670 by 891, we get 7 with a remainder of 433.
The number 7 becomes the next digit in our result. 
Result so far: 74751.637
The remainder is 433 after subtracting 6237 from 6670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 12:
891 goes into 4330 4 times with a remainder of 766.
Write down 4 as next digit of the result. 
Result so far: 74751.6374
Deduct 3564 from 4330 and we're left with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Let's proceed to step 13:
891 can be fit into 7660 8 times, resulting in a remainder of 532.
Use 8 as the next digit of our solution. 
Result so far: 74751.63748
Deduct 7128 from 7660 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 14:
891 can be fit into 5320 5 times, resulting in a remainder of 865.
Use 5 as the next digit of our solution. 
Result so far: 74751.637485
Subtract 4455 from 5320 to get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Moving on to step 15:
891 goes into 8650 9 times with a remainder of 631.
Write down 9 as next digit of the result. 
Result so far: 74751.6374859
Subtracting 8019 from 8650 leaves us with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Going ahead to step 16:
891 goes into 6310 7 times with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 74751.63748597
Subtract 6237 from 6310 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 74751.63748597, and the remainder is 7.3e-08.
