45668661 ÷ 851 
We want to figure out the number of times 45668661 can be divided by 851.

Advancing to step 1:
851 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 851

On to step 2:
If we divide 45 by 851, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 851

Going ahead to step 3:
If we divide 456 by 851, we get 0 and a remainder of 456.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 456, we get 456.
Bring next digit (6) of the dividend behind the 456 and repeat the process: 4566 / 851

Step 4:
851 goes into 4566 5 times with a remainder of 311.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4255 from 4566 leaves us with 311.
Bring next digit (8) of the dividend behind the 311 and repeat the process: 3118 / 851

Advancing to step 5:
851 goes into 3118 3 times with a remainder of 565.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 2553 from 3118 to get 565.
Grab the next digit (6) from the dividend, add it to 565, then carry on: 5656 / 851

Advancing to step 6:
851 can be fit into 5656 6 times, resulting in a remainder of 550.
Write down 6 as next digit of the result. 
Result so far: 536.0
Subtract 5106 from 5656 to get 550.
Bring next digit (6) of the dividend behind the 550 and repeat the process: 5506 / 851

On to step 7:
When dividing 5506 by 851, we get 6 with a remainder of 400.
Record the quotient 6 as the next digit in the result. 
Result so far: 5366.0
The remainder is 400 after subtracting 5106 from 5506.
Grab the next digit (1) from the dividend, add it to 400, then carry on: 4001 / 851

Advancing to step 8:
The number 851 fits into 4001 4 times, leaving a remainder of 597.
Write down 4 as next digit of the result. 
Result so far: 53664.0
If we take 3404 away from 4001, we end up with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Advancing to step 9:
851 goes into 5970 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 53664.7
The remainder is 13 after subtracting 5957 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
130 divided by 851 is 0 with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 53664.7
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
851 goes into 1300 1 times with a remainder of 449.
The next digit of our result is 1. 
Result so far: 53664.701
The remainder is 449 after subtracting 851 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 12:
4490 divided by 851 is 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 53664.7015
If we subtract 4255 from 4490, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 13:
851 goes into 2350 2 times with a remainder of 648.
Use 2 as the next digit of our solution. 
Result so far: 53664.70152
Subtracting 1702 from 2350 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 14:
6480 divided by 851 is 7 with a remainder of 523.
Record the quotient 7 as the next digit in the result. 
Result so far: 53664.701527
Subtracting 5957 from 6480 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 15:
The number 851 fits into 5230 6 times, leaving a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 53664.7015276
Subtract 5106 from 5230 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 16:
851 can be fit into 1240 1 times, resulting in a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 53664.70152761
If we subtract 851 from 1240, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Our division results in 53664.70152761 with a remaining 3.89e-07.
