We look at the division of 85977361 by 669 
Our goal is to divide 85977361 by 669.

Step 1:
8 divided by 669 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 669

On to step 2:
The number 669 fits into 85 0 times, leaving a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 669

On to step 3:
The number 669 fits into 859 1 times, leaving a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 669 from 859 to get 190.
Grab the next digit (7) from the dividend, add it to 190, then carry on: 1907 / 669

Moving on to step 4:
669 can be fit into 1907 2 times, resulting in a remainder of 569.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1338 away from 1907, we end up with 569.
Bring next digit (7) of the dividend behind the 569 and repeat the process: 5697 / 669

On to step 5:
The number 669 fits into 5697 8 times, leaving a remainder of 345.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtract 5352 from 5697 to get 345.
Fetch the next digit (3) from the dividend, attach it to 345 and continue: 3453 / 669

Advancing to step 6:
669 goes into 3453 5 times with a remainder of 108.
The number 5 becomes the next digit in our result. 
Result so far: 1285.0
Subtracting 3345 from 3453 leaves us with 108.
Include the next digit (6) from the dividend after 108, then repeat: 1086 / 669

On to step 7:
If we divide 1086 by 669, we get 1 and a remainder of 417.
The next digit of our result is 1. 
Result so far: 12851.0
Subtracting 669 from 1086 leaves us with 417.
Fetch the next digit (1) from the dividend, attach it to 417 and continue: 4171 / 669

On to step 8:
669 can be fit into 4171 6 times, resulting in a remainder of 157.
Write down 6 as next digit of the result. 
Result so far: 128516.0
Subtracting 4014 from 4171 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
If we divide 1570 by 669, we get 2 and a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 128516.2
Subtracting 1338 from 1570 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
669 can be fit into 2320 3 times, resulting in a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 128516.23
The remainder is 313 after subtracting 2007 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 11:
669 can be fit into 3130 4 times, resulting in a remainder of 454.
The number 4 becomes the next digit in our result. 
Result so far: 128516.234
Deduct 2676 from 3130 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 12:
4540 divided by 669 is 6 with a remainder of 526.
Put 6 as the next digit of the answer. 
Result so far: 128516.2346
If we subtract 4014 from 4540, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 13:
When dividing 5260 by 669, we get 7 with a remainder of 577.
Put 7 as the next digit of the answer. 
Result so far: 128516.23467
If we subtract 4683 from 5260, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 14:
669 goes into 5770 8 times with a remainder of 418.
The next digit of our result is 8. 
Result so far: 128516.234678
If we subtract 5352 from 5770, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 15:
669 can be fit into 4180 6 times, resulting in a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 128516.2346786
If we subtract 4014 from 4180, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 16:
669 can be fit into 1660 2 times, resulting in a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 128516.23467862
Subtract 1338 from 1660 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The quotient of the division is 128516.23467862, and the remainder is 3.22e-07.
