We're dividing 83749621 by 699 
We want to figure out the number of times 83749621 can be divided by 699.

On to step 1:
When dividing 8 by 699, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 699

Advancing to step 2:
When dividing 83 by 699, we get 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 699

Step 3:
837 divided by 699 is 1 with a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 699 from 837 and we're left with 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 699

Going ahead to step 4:
When dividing 1384 by 699, we get 1 with a remainder of 685.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 685 after subtracting 699 from 1384.
Append the next digit (9) from the dividend to 685 and continue with: 6859 / 699

Going ahead to step 5:
699 goes into 6859 9 times with a remainder of 568.
Write down 9 as next digit of the result. 
Result so far: 119.0
Deduct 6291 from 6859 and we're left with 568.
Grab the next digit (6) from the dividend, add it to 568, then carry on: 5686 / 699

Let's proceed to step 6:
5686 divided by 699 is 8 with a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 1198.0
If we take 5592 away from 5686, we end up with 94.
Bring next digit (2) of the dividend behind the 94 and repeat the process: 942 / 699

Going ahead to step 7:
If we divide 942 by 699, we get 1 and a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 11981.0
Deduct 699 from 942 and we're left with 243.
Append the next digit (1) from the dividend to 243 and continue with: 2431 / 699

Moving on to step 8:
When dividing 2431 by 699, we get 3 with a remainder of 334.
Record the quotient 3 as the next digit in the result. 
Result so far: 119813.0
If we subtract 2097 from 2431, 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.

Let's proceed to step 9:
3340 divided by 699 is 4 with a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 119813.4
If we take 2796 away from 3340, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 10:
699 goes into 5440 7 times with a remainder of 547.
Write down 7 as next digit of the result. 
Result so far: 119813.47
If we subtract 4893 from 5440, we get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Step 11:
The number 699 fits into 5470 7 times, leaving a remainder of 577.
Record the quotient 7 as the next digit in the result. 
Result so far: 119813.477
Deduct 4893 from 5470 and we're left with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Our division results in 119813.477 with a remaining 0.0577.
