10120900 divided by 7 
We want to figure out the number of times 10120900 can be divided by 7.

Moving on to step 1:
1 divided by 7 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 7

Going ahead to step 2:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 7 away from 10, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 7

On to step 3:
When dividing 31 by 7, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 28 from 31 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 7

Step 4:
7 can be fit into 32 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 144.0
If we take 28 away from 32, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 7

On to step 5:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1445.0
Subtracting 35 from 40 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 7

Moving on to step 6:
7 can be fit into 59 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 14458.0
Subtracting 56 from 59 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 7

Moving on to step 7:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 144584.0
If we take 28 away from 30, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 7

Going ahead to step 8:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1445842.0
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1445842.8
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1445842.85
Subtracting 35 from 40 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1445842.857
If we take 49 away from 50, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
7 goes into 10 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1445842.8571
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1445842.85714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 1445842.857142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 15:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1445842.8571428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 16:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1445842.85714285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 1445842.85714285, and the remainder is 5e-09.
